Error while trying to read volVectorField

blackbirdinapie · October 6, 2011, 17:12

Hello,

I am trying to read a volVectorField "D" from the output of solidDisplacementFoam. However, I get a strange error. This is error was also seen in the following thread http://www.cfd-online.com/Forums/ope...ntialfoam.html
but was not solved. I paste the whole error message below.

Hi
It seems that you want to cast one type to volVectorField that this type casting is not permitted.
Good luck

Can you post your code here?

T.

blackbirdinapie · October 11, 2011, 11:20

Thanks for your replies! The code is trying to read an existing volVectorField from a given directory..
The code is

#include "fvCFD.H"
#include "Switch.H"

#include <fstream>
#include <sstream>
#include <vector>
#include <string>
#include <algorithm>
#include <iostream>

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

double round (double val, int digits) {
std:

stringstream oss;
oss.precision(digits);
oss.setf(std::ios::fixed);
oss << val;
std::istringstream iss;
iss.str(oss.str());
double rounded;
iss >> rounded;
return rounded;
}

int main(int argc, char *argv[])
{

argList::validArgs.append("numIter");
argList::validArgs.append("face");

#include "setRootCase.H"
#include "createTime.H"
#include "mesh.H"
#include "createFields.H" <---------------- This is the line with problem

Inside createFields.H

volVectorField D1
(
IOobject
(
"D",
"./1",
mesh,
IOobject::MUST_READ,
IOobject::NO_WRITE
),
mesh
// dimensionedVector("D", dimensionSet(0,1,0,0,0,0,0), vector(0.0,0,0))
);

There already exists a D volVectorField (with boundaryField of type tractionDisplacement) , and code just tries to read it. I have a feeling this has something to do with the tractionDisplacement BC, because when reading a volVectorField with boundaryField of another type, the code has no problem.

I greatly appreciate all the help! Thanks!

Sujan

tomislav_maric · October 12, 2011, 04:08

Could you pack the case and the whole app and upload it in your post? This way I don't have to reproduce your createFields.H and the tutorial case...

T.

blackbirdinapie · October 12, 2011, 15:56

Hi T,

Thanks a lot for your help.

I have uploaded both the case on which I am trying to run my app (BearingPlateBM), as well as the app itself (gapField2). The command to run the app is "gapField2 1 gen" on rapidshare in the link below. They were too large to attach with this message

.

https://rapidshare.com/files/44870168/OF.zip

I investigated it more, and it really seems to be a problem of the tractionDisplacement BC, especially when the traction field on the boundaries is non - zero

Thanks a lot once again!! Please let me know if you have questions regarding running the case.

Sujan

tomislav_maric · October 14, 2011, 06:16

Hi,

you seem to be reading the field D from the directory "1", I have opened the file and I saw this:

Code:

53611     forcePoint
153612     {
153613         type            tractionDisplacement;
153614         traction        nonuniform 0();
153615         pressure        nonuniform 0();
153616         value           nonuniform 0();
153617     }
153618     junk
153619     {
153620         type            tractionDisplacement;
153621         traction        nonuniform 0();
153622         pressure        nonuniform 0();
153623         value           nonuniform 0();
153624     }

"nonuniform0()" : where does it come from? This seems wrong. Also, why are some patches missing? What exactly does your program do? What is the purpose of the boundary condition?

I've used gdb on the program and you have to go deeper than createFields:

Code:

108        return readField(dictionary(is));

this is the line of the GeometricField.H, which menas that the field D is failing because a bad dictionary entry. My guess is nonuniform 0(); key-value pair.

Can you change this and let me know what happens?

Best,
Tomislav

blackbirdinapie · October 14, 2011, 15:16

Hi T.

Thanks for checking it out. Actually, this part of the code is a part of a larger project that i am working on for my research. Essentially it generates a Compliance Matrix, using a variant of the solidDisplacementFoam solver.

The D file in ./1 is an output of the stress solver. Actually, on my personal Ubuntu 10 install the gapField code works well if you remove the first line from the ./Make/files text file.. i.e delete <tractionDisplacement/tractionDisplacementFvPatchVectorField.C>.

However, on a Dell Compute Cluster running Red Hat Enterprise Linux 5.5, this fix does not work. I am very confused about this.

Please try to delete <tractionDisplacement/tractionDisplacementFvPatchVectorField.C> from Make/files and then try running gapField. Since it runs when compiled in a slightly different way, I dont think the problem is in the "D" file. What do you think?

Thanks a lot for your help,

Sujan

Hi Sujan,

there is something wrong with your mesh and boundary conditions, as I have noticed already here, what checkMesh tells me:

HTML Code:

Checking topology...
 ****Problem with boundary patch 13 named forcePoint of type patch. The patch should start on face no 265317 and the patch specifies 0.
Possibly consecutive patches have this same problem. Suppressing future warnings.
 ***Boundary definition is in error.


--> FOAM FATAL ERROR: 
attempt to access element from zero sized list

    From function UList<T>::checkIndex(const label)
    in file /home/tomislav/OpenFOAM/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/UListI.H at line 113.

Besides, try copying the field "D" from the directory "0" to the directory "1". When you do this, the application works fine. Again, this means that there is a problem with reading the field. Never question the Gnu Debugger... it is always right

Check your mesh, check the boundary conditions and see why do you get a messed up field D in the directory "1". There is something seriously wrong with the boundary conditions of that field. Value "nonuniform 0();" makes no sense... it is an empty non-uniform list, so there has to be a bug somewhere. My suggestion: check the mesh and the boundary conditions, concentrate on the output that results with the "1" directory. The error is definitely in reading the field (boundaries are ill defined). As for why the application works without the defined boundary condition: I don't know, and in the light of what I have seen: it's not important at all... concentrate on the errors above.

Hope this helps,
Tomislav

Hi Tomislav,

Thanks a lot for your replies. I will check my case out following your advice and keep you informed on what I see. Thanks a lot for your help.

However, the problem with the gapField2 application remains. I have uploaded
the new case and the application again on rapidshare. [execution on command line is "gapField2 2000 gen"]. The field D is in the ./2000 directory.

https://rapidshare.com/files/3769907155/CFDonline.zip

I am puzzled, as I mentioned in my previous post by the following -

Quote:

However, on a Dell Compute Cluster running Red Hat Enterprise Linux 5.5, this fix does not work. I am very confused about this.

However, I also agree with you that Value "nonuniform 0();" doesnt make sense. However, the code works for me if compiled in a slightly different way!!

Please let me know what you think. Thanks again,

Sujan

tomislav_maric · October 21, 2011, 04:36

Well,

why do you have a patch of length "0" called "junk"?

From the constant/polyMesh/boundary:

Code:

189 junk
190 {
191 type
192 patch;
193 nFaces
194 0;
195 startFace
196 265317;
197 }

and, of course, then you have the "D" field defined poorly, because for this patch, you get the following BC values in the directory 2000:

Code:

153597     junk
153598     {
153599         type            tractionDisplacement;
153600         traction        nonuniform 0();
153601         pressure        nonuniform 0();
153602         value           nonuniform 0();
153603     }

And here's where the illogical "nonuniform 0();" appears... either remove the "junk" patch, or make the BC recognize the patch size and do nothing for that specific patch.

Hope this helps,
Tomislav

Dear all,

I have the same error

Have anyone found the cure?

The custom solver seems OK as it works well on other geometries. This error only happens when trying to continue from a previous run and at reading the D field. I am using 2.1.x on Ubuntu 12.04.

I even removed all fancy BCs and kept all as fixedValue.

Error:

However tomislav expatiated a lot and in my experience he is an expert, but from the error you are getting:
type N4Foam5token8CompoundINS_4ListIdEEEE to type N4Foam5token8CompoundINS_4ListINS_6VectorIdEEEEEE
, aren't you trying to fit a scalar field into a vector one?

Nope!

Actually it has to do with the tractionDisplacement BC at one of its constructors. The error is not consistent (does not appear for all problems). I think it has to do with:

Code:

tractionDisplacementFvPatchVectorField::
tractionDisplacementFvPatchVectorField
(
    const fvPatch& p,
    const DimensionedField<vector, volMesh>& iF,
    const dictionary& dict
)
:
    fixedGradientFvPatchVectorField(p, iF),
    traction_("traction", dict, p.size()),
    pressure_("pressure", dict, p.size())
{
    //    fvPatchVectorField::operator=(patchInternalField());
    fvPatchField<vector>::operator==(Field<vector>(p.size(), pTraits<vector>::zero));
    gradient() = vector::zero;
}

I changed the line but still getting the same error. I just cannot track where the refCast is taking place.

Hi Hisham,

I have made a quick look, and the only casts, which I have been able to come across are the following (at least those in the direct line of search):

Code:

fvPatchField.H:            (dynamic_cast<const fvPatchFieldType&>(ptf), p, iF, m)

and

Code:

fixedGradientFvPatchField.C:        refCast<const fixedGradientFvPatchField<Type> >(ptf);

and then probably the one, which is the most interesting, because it is related to your adddictionaryConstructorToTable:

Code:

./finiteVolume/interpolation/interpolation/interpolation/interpolation.H:interpolation<Type>::adddictionaryConstructorToTable<SS<Type> >

Your boundary condition has a reference to fvPatch through your fvPatchField, and the former connects to "class surfaceInterpolation". Why you are having problems is beyond my understanding - especially since you have mixed results.

There are quite a few "adddictionaryTo...", but the rest are related to either lagrangian or thermo-physical models.

Could you elaborate on (i) how you are reading the field in terms of code and (ii) given an example of a field, which is improper read.

Good luck

Niels

Hi Niels,

Thanks a lot for the effort. I will surely consider those. I just think I should do some more experimenting before I go into code modification. I hope I am not trying to fix what is already fixed. I took the geometry to a different input files and it seems to be working. Well not working I just have other errors

. So until I am sure about the error I will not change the code.

It just strikes me how this kind of error can arouse from user input

The code that issues the error is (simply):

Code:

volVectorField D  
(     
 IOobject     
 (         
 "D",         
 runTime.timeName(),        
  mesh,        
  IOobject::MUST_READ,         
 IOobject::AUTO_WRITE      
),     
 mesh 
 );

when the tractionDisplacement BC is used. However, now it seems to be more likely an input error.

Thanks again and I will post if I knew what caused this madness!

Hisham · March 5, 2013, 11:11

Hi Niels,

I think it is something with the use of gmshToFoam - splitMesh combination. It seems that every time splitMesh is used (after gmshToFoam), it does not produce the same result (for the same files) for some unknown reason and it, sometimes, creates one crazy shaped element on the split surface that connect both regions on both sides of the split. When that element is produced, the error happens for continuation of solution from a previous one. If the mesh survived splitMesh without that element, all works well.

I think it has to do with quality of the mesh near split surfaces.
This is what seems to be the problem!

Thanks again and best regards,
Hisham

The command to run the app is "gapField2 1 gen" on rapidshare in the link below. They were too large to attach with this message . https://rapidshare.com/files/44870168/OF.zip I investigated it more, and it really seems to be a problem of the tractionDisplacement BC, especially when the traction field on the boundaries is non - zero Thanks a lot once again!!

This seems wrong. Also, why are some patches missing? What exactly does your program do? What is the purpose of the boundary condition? I've used gdb on the program and you have to go deeper than createFields: Code: 108 return readField(dictionary(is)); this is the line of the GeometricField.H, which menas that the field D is failing because a bad dictionary entry. My guess is nonuniform 0(); key-value pair. Can you change this and let me know what happens? Best, Tomislav Last edited by tomislav_maric; October 14, 2011 at 06:17. Reason: More BC info...

blackbirdinapie New Member Join Date: Oct 2011 Posts: 10 Rep Power: 15	Hi T. Thanks for checking it out. Actually, this part of the code is a part of a larger project that i am working on for my research. Essentially it generates a Compliance Matrix, using a variant of the solidDisplacementFoam solver. The D file in ./1 is an output of the stress solver. Actually, on my personal Ubuntu 10 install the gapField code works well if you remove the first line from the ./Make/files text file.. i.e delete <tractionDisplacement/tractionDisplacementFvPatchVectorField.C>. However, on a Dell Compute Cluster running Red Hat Enterprise Linux 5.5, this fix does not work. I am very confused about this. Please try to delete <tractionDisplacement/tractionDisplacementFvPatchVectorField.C> from Make/files and then try running gapField. Since it runs when compiled in a slightly different way, I dont think the problem is in the "D" file. What do you think? Thanks a lot for your help, Sujan

From the constant/polyMesh/boundary: Code: 189 junk 190 { 191 type 192 patch; 193 nFaces 194 0; 195 startFace 196 265317; 197 } and, of course, then you have the "D" field defined poorly, because for this patch, you get the following BC values in the directory 2000: Code: 153597 junk 153598 { 153599 type tractionDisplacement; 153600 traction nonuniform 0(); 153601 pressure nonuniform 0(); 153602 value nonuniform 0(); 153603 } And here's where the illogical "nonuniform 0();" appears... either remove the "junk" patch, or make the BC recognize the patch size and do nothing for that specific patch. Hope this helps, Tomislav
