I bought a quadro P4000, but I can't run it with ansys Mechanical. It seems some problem with comunication between ansys and the graphic card. i installed last version of cuda 9.2, but without results. Any ideas?! Here following the message I got from the solver:

I installed graphic drivers 397.93 version and cuda 9.2.88.1 version. Is there any driver version that let the graphic card run into solution?


Thanks in advance

It looks like you are running ANSYS 18.0, what version of Windows are you running?

I checked the tested GPU platform support for 18.0 and under Windows 7, the Quadro 4000 was tested with Mechanical APDL.  That is a different card than a QUADRO P4000.

There is this note: "ANSYS Mechanical APDL supports NVIDIA's CUDA-enabled Tesla and Quadro series workstation and server cards. When using the sparse solver or eigensolvers based on the sparse solver with NVIDIA cards additional considerations apply (please consult the ANSYS installation guide for details)."

Under Analysis Settings, try setting the Solver Type to Iterative, then check the Solution Output to make sure it is using the Iterative PCG solver. You can't use the Iterative PCG solver if you have joints in your model, for example. The Iterative solver may work on a GPU where the Direct Sparse solver does not.

The QUADRO P4000 is on the tested list of graphics adapters for 19.0 This is the list for graphics on the display which is separate from the use of a GPU to acceleration the solving process.

The tested GPUs for ANSYS 19.1 are only Tesla cards, and only the V100 was tested under Windows Server 2016. Did you consider purchasing that model of GPU?

Here is a relevant post.

I'm running windows 10 pro.... V100 is a little bit expensive for my pocket

What happened with you switched to the Iterative solver?

I did a study on Version 16 on the effect of Tesla K40 GPU on 9 of my structural models. Adding one GPU was worse on 8 of my models compared with adding one more CPU core.
