Dear Foamers,

i'm using OpenFOAM 2.2.2. In order to lower the interpolation errors of mapFields near walls I am trying to add a new interpolation scheme like this was done here:

http://www.cfd-online.com/Forums/ope...mapfields.html

Therefore I need to change mapFields itself as well as some files in the sampling library (inside meshToMeshInterpolation).
I want the original mapFields executable and sampling libraries to be unchanged. Thats why I copied the mapFields directory as well as the whole OpenFOAM src-folder (including 'sampling') to another location.

To get a smooth start I changed the names 'mapFields' to mapFieldsMJ and did some changes to the Make-files. Now they look like that:

mapFieldsMJ/Make/files:

mapLagrangian.C
mapFieldsMJ.C

EXE = $(FOAM_USER_APPBIN)/mapFieldsMJ

mapFieldsMJ/Make/options:

EXE_INC = \
    -I$(LIB_USER_SRC)/meshTools/lnInclude \
    -I$(LIB_USER_SRC)/lagrangian/basic/lnInclude \
    -I$(LIB_USER_SRC)/finiteVolume/lnInclude \
    -I$(LIB_USER_SRC)/sampling/lnInclude

EXE_LIBS = \
    -L$(FOAM_USER_LIBBIN) \
    -lsamplingMJ \
    -lmeshTools \
    -llagrangian \
    -lfiniteVolume \
    -lgenericPatchFields

$LIB_USER_SRC/sampling/Make/files:

 ... (only last line changed) ...

meshToMeshNew = meshToMeshInterpolation/meshToMeshNew
$(meshToMeshNew)/meshToMeshNew.C
$(meshToMeshNew)/meshToMeshNewParallelOps.C

LIB = $(FOAM_USER_LIBBIN)/libsamplingMJ

$LIB_USER_SRC/sampling/Make/files:

EXE_INC = \
    -I$(LIB_USER_SRC)/finiteVolume/lnInclude \
    -I$(LIB_USER_SRC)/meshTools/lnInclude \
    -I$(LIB_USER_SRC)/surfMesh/lnInclude \
    -I$(LIB_USER_SRC)/fileFormats/lnInclude \
    -I$(LIB_USER_SRC)/triSurface/lnInclude \
    -I$(LIB_USER_SRC)/conversion/lnInclude \
    -I$(LIB_USER_SRC)/lagrangian/basic/lnInclude

LIB_LIBS = \
    -lfiniteVolume \
    -lmeshTools \
    -lsurfMesh \
    -lfileFormats \
    -ltriSurface \
    -llagrangian \
    -lconversion

Afterwards I tried to compile the renamed code and to run it. The compilation of libsamplingMJ (first) and mapFieldsMJ (second) gave no error. But using mapFieldsMJ in a test case afterwards failed and returned the following error message:

*** glibc detected *** mapFieldsMJ: corrupted double-linked list: 0x00000000013694e0 ***

The original mapFields still works well in that test case.

I tried to get rid of this problem without success - getting a little bit frustrated since I did not even change anything inside the code.

Could you please help me? I would be very grateful if anyone could give me a hint how to solve the problem.

Your Make deep revision!
Here are few general points,

• You don't have to copy the complete source of OpenFOAM.
• Copy what you need to modify only and rename the classes.
• Link back to original OpenFOAM source and libraries.

The problem is simple you compiled the same classes twice with the same names and when you link the new ones to any case the solver cannot decide which one to use.

Thank you very much for this answer.

Please don't blame me for my inexperience, but actually I'm still not sure what I did wrong. Which classes did I compile twice? Do I have to rename everything in the sampling-directory?

[hk318i]

No worries, we all are on OpenFOAM learning curve.
The classes of sampling library are recompiled without renaming. You don't need them all, you only need meshToMesh class. Before you processed further in this issue, it is better to test the new versions of OpenFOAM because this class had major updates since OF2.2. Even in OF2.2, you will notice that there are new meshToMesh class.

The easiest and most straight forward way could be copy and rename meshtoMesh and included directly in your application.
