I am woefully undereducated in the science of parallel processing, but I feel you may be onto something. Our companies spend so much money on these fancy Quadro GPUs, it's a shame the software doesn't take advantage of the CUDA platform.
I can't imagine that it will not be implemented soon. SPR 533330 has the 'enhancement status' set to 'yes'.
Does SOLIDWORKS Flow Simulation 2014 take advantage of GPU?
No, SOLIDWORKS Flow Simulation 2014 does not support GPU. Our product development team is reviewing the enhancement requests asked by our customer. SolidWorks may support GPU in the later version.
