I run a simulation of helium leakage in a room. However, I found there is unreasonable velocity vector near the wall. Especially the ground and the ceiling. The velocity vector is normal inward into the wall. This is not right. And I don't know why? Below is the cross view of the domain. and zoom of the ground area. Please let me know of you idea. I am stuck here and my boss is pushing me...... Oppessssssss
