Interpolation problem

Please login with a confirmed email address before reporting spam

Hello:

This simulation model requires an interpolation file of the velocity field on boundary, it is able to be imported. Then I start to run the model, and, it failed :(
I am confused by the error message :
Undefined value found.
- Detail: Undefined value found in the constraint residual vector: NaN or Inf in vector.

I think it is caused by the interpolation file, it doesn't show the velocity field correctly, but ,why?
Can anyone help me to figure out the problem?

Sincerely
