problem with Axisymmetry simulation
 
hi
I'm working on simulation of fluid in cylindrical vessel . I used Axisymmetric for that . when i run the calculation it keep giving (Error: Divergence detected in AMG solver: x-momentum) ,i used a fine mesh and reduced under relaxtion factor to 0.1 and it still give the same error .
when i switched to cartesian with the same setting it give the solution and the convergence was established !
can u help me please with this
thanx in advance
