Flow moves along the surface
 

Hello,

I am modeling steel filling up a chamber. My problem is that when steel falls inside the chamber it does not fill it and it sticks to the walls and goes out (Please see image).

I have used VOF and Eulerian VOF two-phase flow models.

I have used fine and coarse meshes.

I have used K-epsilon and K-omega SST models.

But I am getting almost the same results. Do you know what is the problem?

Thanks
