Hi guys! Greatly need a BIG hand here. I have never successfully setup parallel computing with GPGPUs on ANSYS Fluent. I have these to note:
1. All NVIDIA with CUDA cores is detected by ANSYS Fluent 18.0 AMG solver and very much compatible; 2. GPU parallel computing allows up to five (5) coupled equations; and 3. CFD pressure coupled solver works fine with GPU computing. I am running a sliding mesh VAWT simulation with a mesh of approximately 2 million cells on a 3.41 GHz 4-core PC with 32 Gb RAM. Without the GPU setting, the simulation works well although at a very low computing turnaround - around 6 to 7 minutes per time step. Setting the GPU up does not run the simulation. Instead I get this error report in the Fluent command line every time: Thrust failure: out of memory File and line number are not available for this exception. AMGX ERROR: file amg\amg_gpu.c line 1027 AMGX ERROR: Thrust failure. The fl process could not be started. MPI Application rank 0 exited before MPI_Finalize() with status 1 Maybe someone out there has made this work. Will appreciate help making me understand the situation or best make GPU computing work for my case. Thanks! |
