It is unlikely, that the line, you have posted, causes Floating Point Exception. As soon as you post stack trace with line numbers it would be easier (maybe the problem in fact is in libccmio and not in converter.

According to your output error happens somewhere between line 667 and 708 (otherwise you get output containing nPoints). Between these two lines there are calls to CCMIOReadProcessor and ReadCells, correct backtrace can show, which one causes FPE.

Thank you alexeym. I am really grateful for your comment. I used the debug version I was provided. I am compiling another version myself.

However, I guess the problem comes from the number of faces as in the mesh I am trying to convert:
95187700 cells, 612345350 faces, 502047784 verts.

And the crashes happens at:
List<label> ccmFaces(size);

Hi, Abe

Did you solve this problem? I have the same problem as you. Specifically, the ccm26toFoam will complain "core dumpFloating point exception (core dumped)" when the mesh size is tens of millions. A small number of mesh is ok.

Could you give me some help?

Best regards,

Jazz
