Dear all,
I have successfully compiled gmsh with the cgns output support. Now, I
am trying to use it, but it is not working :
|$ gmsh case.geo -2 -o case.cgns -format cgns
...
Info : Done meshing 2D (0.543918 s)
Info : 30693 vertices 49134 elements
Info : Writing 'case.cgns'...
Warning : CGNS I/O is at an "alpha" software stage
Erreur de segmentation|
I run the commands 'gdb gmsh' and 'run case.geo -2 -o case.cgns -format
cgns' to get the following trace :
|(gdb) backtrace

I looked into the source file
|/home/msoismie/local/usr/gmsh-2.6.1-source/Geo/GModelIO_CGNS.cpp |in
order to try to understand my mistake, but I did not find the |case
write_CGNS_zones<2u>| (I have found only: |write_CGNS_zones<2>| and
|write_CGNS_zones<3>|).
After reading the warning telling that 'the CGNS I/O is at an alpha
software stage', I understand that the CGNS I/O has to be used
carefully. Do you have any idea or suggestion that could help to solve
this problem and allow me to use the CGNS I/O ?
Thank you in advance for your helpfull answers.
Best regards,
Matthieu Soismier
