Hi,
on our Linux cluster we have to start cfx5pre and cfd5post with "-gr mesa" to be able to start the programs. If we dont, the terminal windows crashes and the ssh connection dies. I suppose it is graphics related and that there is something that isn't (properly?) installed on the cluster, anyone have an idea of what it can be? cheers Lance |

The default option for CFX-Pre and Post uses OpenGL. Most terminals don't support OpenGL. That is why you need to use the mesa graphics option.

Glenn,
I understand that, but the thing is that I can start the program and load a case, and then it crashes. If openGL werent supported I shouldnt be able to start the program at all, right? Or am I missing something here? |

Yes, if openGL is not supported it should not even start. I can't explain it crashing when you open something.

I had similar issue. I needed an update of graphics card driver. (As far as I understood it was firmware error in the OpenGL). Consequence was an error for specific OpenGL calls.

Thanks for the info joey, thats what I expected... so far I haven't been able to get any error messages when the program crashes since every terminal window dies, but I'll hopefully figure something out.
