segmentation fault
 
Hello,

I run cases for liquid film recently using interDyMFoam. There's no problem when I run the cases, but when I try to reconstruct fields, it shows the following error:
#0 Foam::error::printStack(Foam::Ostream&) in "/home/huxiaoxi/OpenFOAM/OpenFOAM-1.7.1/lib/linux64GccDPOpt/libOpenFOAM.so"
#1 Foam::sigSegv::sigSegvHandler(int) in "/home/huxiaoxi/OpenFOAM/OpenFOAM-1.7.1/lib/linux64GccDPOpt/libOpenFOAM.so"

Segmentation fault

Can anyone help me?

Thanks.

Have you reconstructed the meshes with reconstructParMesh? Last time I looked this was necessary

yes, I did.

That kind of information would have been nice in the first place as it is a common pitfall.

Next question: are you reconstructing all time-steps at once (that is another thing that doesn't work as far as I remember). Can't tell from whatyou posted if the problem occured during the reconstruction of the first time-step or later

If its not that I can only tell you what I tell all people that have a segfault: Compile a Debug-version of OF. Then the dump will also show line numbers and things get interesting

How can I compile a debug-version of OF? By the way, I am using the version 1.7.1? Is it possible to have the bug for this version?
