Summary

Water mixed with mud flows in from the region "inlet" at (0.0191, 0, 0) m/s and out from the region "outlet". The region "top" is assumed to be a slip wall, and the other regions, "bottomWall" and "endWall", are assumed to be no-slip walls. The calculation is performed as a two-dimensional problem with a single mesh in the Z direction.

Model Model

The meshes are as follows, and the number of mesh is 8000.
