Prerequisites:
GPU Solving is supported for Nvidia Quadro Graphics Cards. Therefore, GPU license(s) need to be available and CUDA Driver needs to be installed.
During the installation of MSC Apex Generative Design the GPU option is activated per default and with this the GPU Solver Service is installed.
If you get the message that the GPU solver engine stopped or could not be started, this indicates an outdated graphics card driver, an update of it should solve the problem.
Activation:
Per default the GPU calculation is activated. To change the setting go to Application Settings - Generative Design Solver. GPU solving should be preferred because of increased solving speed. Have a look at our performance comparison between different hardware setups.
The CPU threads should be defined in a GPU calculation as well because they are used to build up the FE-matrix and the set value is important for CPU as well as GPU computing.
