Hi,

I am trying to simulate sloshing in rotating cube (±30 degrees) (2D).
The cube is rotating around center of lower side.


mesh :structured
Homogeneous Model
Turbulence : None (Laminar)

Unfortunately when cube rotates, the free surface gets irrational slope, and seems that water does not transfer properly between parts ( left and right of wall) \
\
\
\
What is the problem?
How can I fix it?

I have tried other turbulence models, but it was not the solution and nothing changed. Even I turned on surface tension, but nothing changed.

Please help me ASAP.
