I am trying to use movingWallVelocity as a base for developing new boundary condition. I started by copying the source code and renamed it and everything inside the source. I prepared the Make folder and compiled it without errors.
The problem is, it is blow-up before finishing the first time step.

I tried it with two different cases which are working fine with the original movingWallVelocity on two different systems on each one I tried it with two OpenFOAM versions; 2.2.x and 2.3.x updated. BTW the two cases use two different solvers.

my Options file is;

EXE_INC = \
    -I$(LIB_SRC)/triSurface/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/OpenFOAM/lnInclude

LIB_LIBS = \
    -lOpenFOAM \
    -lfiniteVolume \
    -ltriSurface \
    -lmeshTools

Actually it is not my first time working with movingWallVelocity, I used it before but when I started adding new modification to my BC. I couldn't run it, therefore I decided to start from scratch.
To reproduce the error you can use the wingMotion tutorial and recompile the original BC in your user folder under different name.

Hi Hassan,

You have copied the entire movingWallVelocity patchField directory to a seperate one in, say, $WM_PROJECT_USER_DIR/src and renamed all occurences of movingWallVelocity to fancyMovingWallVelocity? Both in the file names as well as in the files itself? And you have changed the target to where the compiled library is then copied to from $FOAM_LIBBIN to $FOAM_USER_LIBBIN?
The error you show is not a compiler error, but a run time error. Have you checked if it is working with movingWallVelocity?

I hope this helps and gives you some pointers, though I have my doubts that the hints are worth anything. Let me know.

Thank you for your response.
That exactly what I did. I run the wingMotion tutorial with movingWallVelocity and it works. But once I changed the BC to mymovingWallVelocity, I get this error.

Also, I removed all the LIB_LIBS options and tried to recompile it and it was successful. Is that normal?!!

Did you manage to reproduce the error?

I recompiled OpenFOAM again then recompiled mymovingWallVelocity and everything is running now!
I fixed the error but still don't understand why it happened.
