[thegauravonline]

I am working on FSI package in foam-extend 3.2 as native openFoam does not support FSI.

Next, I wish to compile the below acoustics library in foam extend. This library was presented in OF workshop 13 and only available for openFOAM 3.

https://github.com/unicfdlab/Trainin...ustics-OF3.0.0

For installing this on foam-extend 3.2, I did try to make some changes in make->options but after a point I am unable to connect the requisite files (mainly rasModel.h).

Can someone please help me in converting the compatibility of the libAcoustics3.0.0 from openFOAM 3 to foam-extend 3.2.

Very Thanks .

Your link is broken.
You should provide more info explayning what you are doing step by step to compile the code, what errors you got and so on.

I am facing issue precisely at this point.

Am at dead end because I am hardly a programmer.

Please help anyone.

[Zeppo]

Okay, as the error states there's no Foam::List<double>::append(Foam::scalar&) in foam-extend (you can find it in OpenFOAM though). If you want to add an element to a List your options are

1) Whenever you need to add a new element you "increase" the list size by 1 and set the element at the last position in the list. This strategy is very-very uneffective from the memory allocation point of view: every time you add a new element a new memory block needed to accomodate list values is allocated. It can hit the performance so bad.

scalarList list;
...
list.setSize(list.size()+1);
list.last() = scalar(1.0);
...
list.setSize(list.size()+1);
list.last() = scalar(2.0);

or you can create a temporary List consisting of a single element and append it to another one

scalarList list;
...
list.append(scalarList(1, 1.0));
...
list.append(scalarList(1, 2.0));

2) If you know the number of elements to append to the list you can "increase" the list size by the number of elements beforehands and add elements later on at their respective positions. This approach is much better and extensively used in foam source code.

List<scalar> list;
list.setSize(list.size()+2);
...
list[0] = scalar(1.0);
...
list[1] = scalar(2.0);

3) An alternative to 1) and 3) is using DynamicList which can perform memory management by itself and you don't need to care much about it

DynamicList<scalar> list;
...
list.append(1.0);
...
list.append(2.0);

Very Thanks to you Sergel.

I am afraid, I think I need to be spoon-fed.

I understand, I need to look into List.c/List.h for the changes or do I?

But how and where to attach the DynamicList for scalar as you said?

I am sorry. I hardly understand the lists and append function of opeFoam background.

Please help.

[Zeppo]

No, you must not make any modifications to any parts of OF (such as List.H, List.C), you have to alter the code you develop.

[thegauravonline]

Oh... I got it wrong way.
okay now I made changes in .h file while initialization of class which reads as:

class SoundObserver
{
    //-
    word name_;

    //-
    vector position_;
    
    //-
    scalar pref_;
    
    //-
    scalar apressure_;

    //-
    scalar atime_;

    //-original
    //List<scalar> p_;

    DynamicList<scalar> p_;
    p_.append(1.0);    
    
    //-original
    //List<scalar> time_; 
    DynamicList<scalar> time_;   
     time_.append(2.0); 

    //-
    label fftFreq_;

    bool checkOrder(scalar size) const;

this gave me following error:

How to proceed?

Thankyou Sergel.

If I were you I would go with the option #1 (inefficient one) which I suggested in my previous post. It would require less modifications to the code compared to what you try to do now replacing List with DynamicList. Find all yours

list.append(value);

and replace them with

list.setSize(list.size()+1);
list.last() = value;

Many Thanks for your help Sergel.

It worked.

I ve narrowed my error log to much lesser now.

Searching for the links of "findPatchID"

[thegauravonline]

Found out that fvboundarymesh file in foam-extend version does not have this initialization that exist in fvboundarymesh file of openfoam3.0.

            //- Find patch index given a name
            label findPatchID(const word& patchName) const;

            //- Find patch indices given a name
            labelList findIndices(const keyType&, const bool useGroups) const;

Should I make changes to foam files. Or is there any other way to specify patches in the code.

[Zeppo]

Right, foam-extend version of fvBoundaryMesh doesn't have member-function findPatchID. Then just copy-paste the very body of openfoam's findPatchID to the point where the function itself is called

label patchId = mesh.boundary().findPatchID(patchName);

->

label patchId = -1;

const fvPatchList& patches = mesh.boundary();

forAll(patches, patchI)
{
    if (patches[patchI].name() == patchName)
    {
        patchId = patchI;
    }
}

Very Thanks Sergel.

It worked smoothly.

The library compiled successfully.


Thanks again.

[thegauravonline]

Every thing was in good shape. The library worked perfectly untill it had to calculate "fft".

Looks like the library had only links and initialization just enough to successfully compile. But it cannot recognize the definitions in foam-extend 3.2.

Executing fft for obs: CurleAnalogy1
Checking order rem=10
icoFsiElasticNonLinULSolidFoam:
  symbol lookup error: 
      /home/iitmech4/foam/iitmech4-3.2/lib/linux64GccDPOpt/libAcoustics.so: 
            undefined symbol:
                _ZN4Foam3fft16reverseTransformERKNS_3tmpINS_5FieldINS_7complexEEEEERKNS_4ListIiEE

I checked and compared fft.h/ fft.c of both OF-3.0 and FE-3.2 but found no relevant differences in them.

What could the problem be in FE-3.2 as the library calculates "fft" flawlessly when I run it in OF-3.0 ?


Thanks.
