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)

    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.
