Design3d stopped due to the following error
 

Dear all:
I modeled on Numeca's Design3D's Tutorial1 and I got an error when I solved using the Screening module.:confused:
The error is as follows：

DESIGN3D STOPPED DUE TO THE FOLLOWING ERROR
No mesh quality report file found or readable.
The flow solver and the post-processing tasks have been skipped.

Do you have any suggestions?
Thanks much！
