Hello!
I am getting this error whenever I read the MESH in fluent. "FLUENT received fatal signal (ACCESS_VIOLATION)" I am using ICEM to create mesh. The mesh is a simplified car geometry with PRISM volume layer on the car surface and the rest of the volume is Tetra/mixed with Meshing Method as Delauny. The symm is the symmetry plane.... The error sequence in FLUENT is: Building... mesh Note: Separating wall zone 20 into zones 20 and 1. symm -> symm (20) and symm:001 (1) Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Please tell me what am I doing wrong and how to fix it... |

Not sure if the same reason is for your case but I have had this problem occur to me many times even though nothing was actually wrong.
In my case, it was either a licensing / mpi error. A loss of network connection often resulted in this error. The error does not pop up immediately and is hard to detect. Sometimes I have been able to keep working, and even started iterating only to have the program crash 15 minutes later (after I have left the working computer). I come back the next day to find out that the simulation never finished! |
