Yes I am trying to perform the simulation but this warning keeps running and it seems that it still has a long time to run. I am wondering isn’t that some of the refinement edges do exceed the wind tunnel and thus the warning came out.
Btw I am now testing for a smaller refinement region and will get back to you soon.
It is better when I scale down the model and set the refinement region smaller. I am wondering how can I bake the airflow arrow into the layer. Is there any ways to do that?
