VWT - Job not started or/and Job waiting

Altair Forum User

Hello,

I tried to simulate the Frontwing of our Formula Student car. I generated a proper Mesh (as you see in the Dropbox link).

However Virtual Wind Tunnel is not calculating even if the Mesh was generated and i have no intersections.

Is there a Problem with positioning or refinement zones?

(VWT Report also in the Dropbox)

Can you send the model to the dropbox below as well? the link you posted doesnt work for me.

Based upon vwtAnalysis.1.Log file, it seems to be a machine related issue. Did you close any windows while running VWT ? Was there any hardare related issue?

Please run the case again to see if the run aborts again at Time Step = 7.

Hello,

thank you for the quick responses and the help. I think it was a hardware problem. I am really happy that my simulation worked.
