Hi guys, anyone know how to properly define settings for best performance on a Nvidia Quadro k4200 in Ansys CFD Post ? I´m trying to animate a pressure contours on CFD Post from a transient analysis... but it takes so long and I don't see in the use graph of the GPU any activity. It is, as if all those 3k and something CUDA cores are totally useless
I don't pretend to use Nvidia K4200 as a GPU for analysis processing (just works over quadro 5000 and/or Tesla), but I guess that a 1000 Euro Graphic card should be able to do some animations and renderings a little faster than a simple 150 euro and 500 MB memory game graphic card

Please any ideas, suggestions?

thank´s

Are you sure that the rendering part is the bottleneck when creating an animation from a set of time steps? From my experience, loading the time steps from hard disk is the time-consuming part here.

Hi, Alex, thanks for your answer. I was guessing the same, however I have 2 SSD drives running on RAID 0 configuration.If what you are saying is true, then for transient analysis postprocessing animations in Ansys CFD , is worthless to spend the money on a Nvidia Quadro K4200.
Any idea on how to make those cuda cores running in order to improve the performance of those renderings?

Recently I switched from a Quadro 600 to a K2200 (skipping the K600 and K620). There is not much speed improvement for usual cfd work. It becomes more intersting when doing volume rendering or using translucency.

So I think that the Quadro K620 is probably enough for most of our work.

Hi Joern, thank´s for the info. However it is sad to know I have waste my money . I probably got into a wrong conclusion after reading some info regarding Ansys and Nvidia, and I took a bad decision. Hopefully this thread will help other people not to do the same mistake.
By any chance, does your nvidia card have some of those cuda cores? If yes, does those cores work when you make some of those volume renderings? Any clue on how to set the settings for maximum performance?

Best regards
