hi some problems with gambi
 
hi

some problems with gambitToFoam here. i created a very simple 2D net in gambit and exported it to mesh01.neu. when i want to convert it there is a SegV which shows like this

hoerl@ubuntu:~/OpenFOAM/hoerl-1.3/run$ gambitToFoam facingstep facing01 facingstep/facing01/constant/polyMesh/mesh1.neu

i also did an strace from gambitToFoam and there it shows me a lot of ENOENT errors like:

access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
open("/home/hoerl/OpenFOAM/OpenFOAM-1.3/lib/linuxGcc4DPOpt/lam-7.1.1/tls/i686/ss e2/cmov/libOpenFOAM.so", O_RDONLY) = -1 ENOENT (No such file or directory)

...
stat64("/home/hoerl/OpenFOAM/hoerl-1.3/run/facingstep/facing01/0/time", 0xbfcc0500) = -1 ENOENT (No such file or directory)



the installation i have is an ubuntu 6.10 in a vmware machine - i did the install the way which is shown here: https://help.ubuntu.com/community/OpenFOAM

is there anything i should have added and is not in this tut!?

kind regards matthias

I've never seen a failure like this: it did the lex all right and then failed in putting the mesh together. As the mesh has points, faces and cells, nothing really comes to mind. Can you show me this mesh? Alternatively, you could compile and run the debug version and post the full trace-back.

BTW, are other applications running OK?

fluentMeshToFoam - means exporting fluent5/6 from gambit and convert it with fluentMeshToFoam - works fine

also working with blockMesh i wanna test

mfg matthias

PS: is there an ability to append files to the messageboard ?!

For the record: this was a 2-D Gambit mesh and cannot be converted: please make it 3-D in Gambit before exporting.

I've fixed some bugs and made a nicer error message instead of segmentation fault.
