Hi everyone,
I am trying to add a new viscosity models.
1- a folder in transportModels./incompressible/viscosityModels was created, including .H, .C, and .dep files of new model.
2- updating transportModels//incompressible/lnInclude files.
3- updating transportModels/incompressible/Make files (adding new model)
4- wmake lisbo incompressible
and the following is what I receive:


transportModels]$ '/home/OpenFOAM/OpenFOAM-1.5/src/transportModels/Allwmake'
+ wmake libso incompressible
Making dependency list for source file viscosityModels/EyringRoelands/EyringRoelands.C
SOURCE=viscosityModels/EyringRoelands/EyringRoelands.C ; g++ -m64 -Dlinux64 -DDP -Wall -Wno-strict-aliasing -Wextra -Wno-unused-parameter -Wold-style-cast -march=opteron -O3 -DNoRepository -ftemplate-depth-40 -I.. -I/home/ahajisha/OpenFOAM/OpenFOAM-1.5/src/finiteVolume/lnInclude -IlnInclude -I. -I/home/ahajisha/OpenFOAM/OpenFOAM-1.5/src/OpenFOAM/lnInclude -I/home/ahajisha/OpenFOAM/OpenFOAM-1.5/src/OSspecific/Unix/lnInclude -fPIC -c $SOURCE -o Make/linux64GccDPOpt/EyringRoelands.o
'/home/ahajisha/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libincompressibleTransportModels.so' is up to date.
+ wmake libso interfaceProperties
'/home/ahajisha/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libinterfaceProperties.so' is up to date.



Everything seems fine, but when I am trying to solve the problem with simpleFoam (EyringRoelands viscosity model) :

Unknown viscosityModel type EyringRoelands
Valid viscosityModels are :

5
(
Newtonian
CrossPowerLaw
BirdCarreau
HerschelBulkley
powerLaw
)


I would appreciate if someone can help me on this.Many thanks;

Have you done: addToRunTimeSelectionTable ?

Just including the header will not put the name of your model into the selection table.

If you used one of the previous models codes to build your own, you may have seen the declaration of the following static members:

defineTypeNameAndDebug(BirdCarreau, 0);

addToRunTimeSelectionTable
(
viscosityModel,
BirdCarreau,
dictionary
);

The last argument includes the Bird-Carreau model and make it available. You must adapt and include this constructor to your model code. Have you done it in your code?

Hoping that it may help.
Best,
Luiz F.

Check the construction of the selection table.

addToRunTimeSelectionTable
(
piezoViscous, ----> it should be viscosityModel...
EyringRoelands,
dictionary
);

Check if it works now.

You see, you are right... Changing only this would not be sufficient. I was about to send you another message.

I checked your code and notice that it is different from the other viscosity models. You don't use a viscosityModel but a piezoViscous instead. That is why the compiler complains that the viscosityModel is not declared. You don't use it at all.

Using your original code, your model should be in the piezoViscous selection table instead of the viscosityModel. I don't have this piezoViscous files, but you should look for its construction keywords. Is it the same as the viscosityModel?

Check this and please return that I am curious .

piezoviscous is another viscosity model which was included in the same viscosity models directory.
The point is, it was written for OF 1.3. I change bot piezoviscous file and EyringRoelands to cope with OF 1.5 viscosity models but I received errors.
Here is piezoviscous.C:

I have changed everything to cope with new version 1.5. Now the only error I get is:

viscosityModels/piezoViscous/piezoViscous.C:49: error: expected constructor, destructor, or type conversion before ‘;’ token
make: *** [Make/linux64GccDPOpt/piezoViscous.o] Error 1


I paste line 40 to line 50 here:

namespace viscosityModels
{
defineTypeNameAndDebug(piezoViscous, 0);

addToRunTimeSelectionTable
(
viscosityModel,
piezoViscous,
dictionary
);
}


Any idea?

Hi,

I am correcting my question in this post. What I posted before was a code written to take pressure into account for viscosity calculation. The problem is, the new models have not been identified by solvers( simpleFoam) as a viscosityModels.
How can I add these models to the list?
Maybe, there would be another step to add pressure to the solver code.

Any idea?

When I run snappyHexMesh, it also stoped with this kind of error, I changed the mesh refinement level, it is solved. I don't know why.
I modified viscosity model based on icoFoam, it is also stoped with this kind of error, I checked and corrected one equation that may have zero on the denominator. it is still not solved.
So I am also facing the problem.
I hope you will find the answer soon.

Hey,
I've compiled a new viscosity model in OpenFOAM 3.0.1 in Ubuntu but I'm not able to see this new model in the viscosity model selection menu.
Can someone help me out here?

Thanks!!

I'm posting here since this is one of the most recent cries for help over "valid viscosityModels are" error message.

Put the new transport model into the source directory:
Code:
/opt/openfoam4/src/transportModels/incompressible/viscosityModels/newModel
newModel.c
newModel.H
If the newModel includes:
addToRunTimeSelectionTable...

Then update the make file by appending the newModel to:
Code:
/opt/openfoam4/src/transportModels/incompressible/make/files
From the transportModels dir, run:
Code:
wmake libso incompressible
Or, compile the individual library (wmake libso from the source folder) and then add the model to controlDict by appending the line:
Code:
libs ( newModel.so );
Permissions error...
Use su or sudo bash. Do not forget to source the openfoam toolbox:
Code:
 . /opt/openfoam4/etc/bashrc
cfdsolver1 and stoneforshizq like this.

Hi foamers,

First of all thank you for your recent replies on this topic.

I don't get the last point made by "open", when he said

"Do not forget to source the openfoam toolbox:
. /opt/openfoam4/etc/bashrc"

Can somebody explain it to me please?

Thanks in advance and have a good week.

Regards.
