Hello,


I am trying to solve a problem of mixing tank with gas sparging from bottom using fluent

1. The problem is modelled as 2D axisymmetric with MRF for impeller.
2. Symmetry along X-axis, Eulerian-Eulerian , Velocity inlet and top surface with degassing BC.
3. Axis and Wall BC for other sides.


Good mesh and K-epsilon is used.


Facing convergence issue especially Continuity.



Is MRF+Eulerian-Eulerian+2d axisymmetric valid?

axis should be chosen along X-axis.
