Overcoming Convergence & Inverted Elements in Mesh while coupling Moving Mesh with Fluid Dynamics

I am trying to couple Moving Mesh with Navier Stokes to model rotation of the container about a horizontal axis and study the motion of the viscous fluid inside. However the model never seems to converge despite my setting the frame to (ale) and setting Non-Ideal and Weak Constraints. Also I have enabled re-meshing. Still I always get some inverted mesh elements and the solver fails to proceed further.
Kindly help me out to figure out the problem and let me know if there is an alternative to attempting the question.
