Vector flow out from enclosure (Why)

yenchin95 · November 25, 2017, 12:54

Hi, i'm a begineer in ANSYS, currently doing a project on aerodynamic drag. As i follow the basic tutorial from the YouTube, and try it on my own, i found this problem and i have no idea how to solve it.

The result (Vector) just run out of the enclosure.

I did my car model in SpaceClaim, and done the enclosure with boolean in DesignModuler.

I have my inlet, outlet, car, and wall(4 sided) named btw. Wall and car is stationary. Inlet with 27.78m/s.

Anyone has idea for this?

Hope to get some reply soon.

Thanks

I think problem with mesh.

It may be due to two problems.
1. Change arrow size( decrease ) of the vector. Then check it once again. Or
2.Mesh problem (association). Check the quality of mesh

It is not really a problem. Size of arrows depends on the scalar value at that point. So for a point inside domain the arrow size is crossing the domain. You can limit this arrow size in visualization. But it is not really a problem.
