Hello I had a few questions while conducting Discovery training yesterday. 1. After importing the Fluid Sample during the training, the following phenomenon occurred when the Mesh was activated in the Refine step. You can see the mesh well in the Mechanical Sample, but the same case as the attached image occurred in the Fluid Sample. intel core i7-11370h / Geforce RTX3070 Laptop 2. Can someone who is using the demo version first, not officially purchasing the Discovery product, sign up for the Discovery Forum and share information? thank you.

Hello smjang

Does same happen with any other fluid files as well? Can you try updating the graphic card driver from NVIDIA website and see if that helps?

2. Can someone who is using the demo version first, not officially purchasing the Discovery product, sign up for the Discovery Forum and share information?

 Ideally there should not be an issue as such, but thanks for highlighting this, I will confirm with the team if this could be an issue. But since this is a sample model, it is highly unlikely to be the case.

Regards.

Hello smjang

Are the results visible to you when you do the run? Or even they are not visible?

Regards.

Hello, I will answer you.

The same problem occurs even after updating to the Nvidia graphics driver uploaded on October 26th. And the result is displayed as Contour in the Solving step.
And I'm having the same problem in the simulation where I wrote the flow domain.

hi, I have the same problem in a mechanical model: mesh suddenly comes up in dots, not showing the volumes of the steel material forms. Did you solve it already?

[smjang]

rigroy 아니오. 우선 저는 Fluid Simulation에서만 발생하였는데 아직 문제가 해결되지는 않았습니다.

[Roy Schilderman]

smjang hmm, I can't read your characters. I guess you mean my simulation is set to "fluid" instead of "structural"? I'll look into this, tried to change this already.

[smjang]

rigroy Sorry. I uploaded it wrong. First of all, I think meshes come out well in Structural analysis. However, the mesh does not come out well in Flunet (Fluid) analysis. Even after updating the current driver, it's still the same. (RTX2060 SUPER)

[Charudatta Bandgar]

I think RTX 3090 is a GeForce card. Discovery may work on GeForce cards, but not officially supported since there is no testing done for the same. And since they have ampere architecture, that could be the reason why there is an issue. Can rigroy confirm if it is the same with you?

Regards.

I have an old Geforce GTX 070 Ti. But it used to work okay.. it looks like it's now showing the mesh as if it was a fluid. Should I reinstall the driver perhaps, to a common WHQL driver?

[Charudatta Bandgar]

rigroy Yes. update the drivers and see if it works. GTX 1070 Ti, right? It is indeed supported. Regards.

[Roy Schilderman]

the update worked! apperently I installed a 'game ready' driver last week, I now installed the 'studio' driver . Both where whql btw. In now have a nice mesh even whithout the results presented.

thanks

[smjang]

This time, I also updated to the driver uploaded on 11/17. (RTX2060 SUPER) But I still have the same problem.

[Roy Schilderman]

did you use the "game ready" drivers? I think they're not ok for Ansys meshes
