problems with interDyMFoam
 
hello together,
i still try to simulate the motion of a body with interDyMFoam. For this I'm using openFOAM 1.6.x. The example case 'floatingObject' (dynamicFvMesh dynamicMotionSolverFvMesh) works well (using Allrun).
But when building my own modell, using the example case as a 'template', interDyMFoam stops with following output:

-------------------------------------------------------------
Selecting dynamicFvMesh dynamicMotionSolverFvMesh
Selecting motion solver: displacementLaplacian

--> FOAM FATAL ERROR:
Not Implemented
Trying to construct an genericFvPatchField on patch floatingObject of field cellDisplacement

From function genericFvPatchField<Type>::genericFvPatchField(con st fvPatch& p, const DimensionedField<Type, volMesh>& iF)
in file fields/fvPatchFields/basic/generic/genericFvPatchField.C at line 45.

FOAM aborting

#0 Foam::error::printStack(Foam::Ostream&) in "/home/of16/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"

and so on ....
----------------------------------------------------------

what I've did:
1. blockMesh (two patches: stationaryWalls & atmosphere)
2. snappyHexMesh (to cut the simple quadratic body -> floatingObject)
3. setFields
4. interDyMFoam

for me it seems as if something is missing ... but what?

Any idea?

Thanks in advance ...

Greetings and bye, Axel

again ... my mistake. I've just found it ...

I forgot to add one library in in the system/controlDict .

Good night!

Hey alexm,

I saw you are using interDyMFoam. Do you create your meshes with snappyhexmes? if so, could you please explain how to you avoid polyhedras.

Cheers in advanced

HI every body

I have a problem in compiling a new solver developed based on interDyMFoam. I get no error in the compiling process and I get .dep file but when I use $FOAM_USER_APPBIN, I do not see my new solver in the list. By the way, I am using openFOAM 2.1.x
Any ideas?:confused:

Regards
Mahyar

Hi again

For more info on the above message, I ran a case using that new solver but I could not see the results in paraview.
By using the paraFoam command I get this error:

--> FOAM Warning :
From function dlOpen(const fileName&, const bool)
in file POSIX.C at line 1175
dlopen error : /home/mahyar/OpenFOAM/mahyar-2.1.x/platforms/linux64GccDPOpt/lib/libuserparticleVolumFraction.so: undefined symbol: _ZN4Foam14viscosityModel30dictionaryConstructorTab lePtr_E

Any Comments?

Thanks
Mahyar
