DirectMapped in FSI problems
 
Hi, I'm trying to model a fluid structure interaction using LES. I generate the turbulence at the inlet implementing a recycling technique (similar to that of Lund et all) using directMapped BC. Now, my mesh has to be able to deform, however when I run my case I get:

Create time

Create dynamic mesh for time = 0

Selecting dynamicFvMesh dynamicMotionSolverFvMesh
Selecting motion solver: laplaceFaceDecomposition


--> FOAM FATAL ERROR:
Unknown faceTetPolyPatchFaceDecomp type directMappedPatch. Valid faceTetPolyPatchFaceDecomp types are :

7
(
wall
processor
wedge
patch
empty
ggi
symmetryPlane
)


From function faceTetPolyPatchFaceDecomp::New(const polyPatch&, const tetPolyBoundaryMeshFaceDecomp&)
in file tetPolyMeshFaceDecomp/tetPolyPatches/faceTetPolyPatch/newFaceTetPolyPatchFaceDecomp.C at line 59.

FOAM exiting

Does this mean that deformable meshes cannot be used with DirectMapped Bc's? Do I have to set three different domains and link them together? (one recycling domain, one fluid domain with deformable mesh and one solid domain)

I will appreciate any help or suggestions. Thanks

Hello,

Unfortunately, I cannot help but I can report a similar error message. I'm attempting to use the regionCouple boundary in OpenFOAM-1.5-dev which throws the same error that you reported. If anyone has an idea of what we're doing incorrectly, I would certainly appreciate a pointer in the correct direction. I've been pouring over the source files to try and gain a better understanding, but I'm still stuck.

Regards
