How can i solve this problem

Use a machine with a supported GPU.

Any another idea?

I have the same error during solution. GTX1050

GTX1050 is not a supported GPU either.
However, I believe there is a way to make it run anyways.
Set an environmental variable: ANSGPU_OVERRIDE=1
You may have to reboot for this to take effect.
Then it may work regardless, however, the performance of that GPU may not be too great.

Alternative solution: don't try to use GPU acceleration

Didn't know that you could force Ansys mechanical to use non-whitelisted GPUs. Is that a new feature, or did I fail to find it for several years?

I think it is an undocumented feature. I found it a long time ago on some forum, and people said it worked after trying it. I never tried it myself though, as I doubt I would see much gain in performance, if any, due to the horrible double precision performance of most gaming cards, or cards not specifically designed for GPU computing. Heck, even the old Tesla cards were not too great if I recall. And their performance was very problem type dependent, and problem size dependent due to their limited RAM.

This feature is documented
