Hi,

Does anyone know what 'segmentation violation' means in ICEM-CFD? I get that message when I try to create the input files for the solver I'm using.

Thanks,

Antonis

Segmentation violation for any program means a memory fault. Accessing beyond the limits of an array, accessing an array that's not allocated, etc.

Hi, Segmentation violation means crash.It means the code behind that command is stucked/disturbed.

Depending on whether you are using ICEM off a server or based on a single machine could be something to due with insufficient memory or file access.
Get it sometimes when I am using it on big meshes and doing lots of dynamic zooming in and outs while its processing a change.

Hi there

I am getting 'segmentation violation' when I try to convert my Pre-Mesh to Multiblock Mesh. It should not be a memory fault, because I tried it with a small mesh and even on a machine with 32GB RAM. I tried it on a Windows and a Linux machine.
I am using ICEM 12.1.

Is it possible that the geometry/blocking is the reason for the problem? Or do you guys have some other hints for me?

I appreciate any effort.

Thx, Robert

Hi

Maybe the replay-function is the problem. I sometimes get weird errors when I am loading a replay-file. Also I cant replay my commands from the beginning to the end. I dont know why this is happening.

I tried building my mesh on ICEM 11.0 without using the replay-function. This time I can create the Multiblock Mesh but I get an error writing the data out (Output/Write Input).

Code:
 Running ICEM CFD/CAE Multi-block Info Vers. 5.0.0

Error in unsh_gsfdims, idomnum=2
Error exit in unsh_gsfdims
Error creating multi-block neutral files...
child process exited abnormally
Done
Done with translation.
I am using Multiblock-info / Nastran solver. It seems that the .dom files were created correctly, but the .topo file isnt complete.

Hi,

Segmentatiion violation error means: it may be geometry size problem or you are not having licence to access.

Hi Raju, thx for your reply.
What does "geometry size problem" mean? Is it that my workstation is too weak (RAM, HDD, CPU) to handle the mesh? I dont think thats the problem.

Thx for the hint with the licencing, we are having a change because of ANSYS 13 and therefore I have problems with the ICEM OUT licence. Maybe there is another problem concerning the creation of the mesh files.
