Hi,

only a stupid question. Can this graphic adapter typical for games help in the calculations? I have seen in the options for the solver in mechanical, that there's an option that supports NVIDIA adapters

In Mechanial: Tools>Solver Properties

Advanced button: Use GPU acceleration if possible: None / NVIDIA

Would improve the speed in the calculations to have this graphic adapter?

Thanks

PS: I have seen that some computer configurations have SLI http://en.wikipedia.org/wiki/Scalable_Link_Interface
That means that the computer has more than one adapter working as one. Would it help or is only for games?

Sounds like you are using ANSYS? Then no that GPU won't help you do calculations. ANSYS only allows Tesla and certain high end Quadro cards to be used as GPU accelerators. If you try to enable it you will just get an error message that says unsupported GPU adapter.

Yes, ANSYS.

Thanks. It only supports Nvidia Tesla and Quadro.

And how's with the NVIDIA Quadro K2000M and NVIDIA Quadro K1000M?

Would they improve anything? I mean the calculations. Or would it be only an imrovement with the design modeler?

Thanks

Well that depends a lot, perhaps you should check out this discussion (near bottom of page 1):

Also SLI or crossfire configurations (running more than one identical graphics card) will help graphics performance. But I think ANSYS only lets you run one GPU per node for GPU computing (unless they have changed it since I last checked)
