UDF Error
I am solving a 2D Axisymmetric Problem . why does it give the below stated error "Error :Divergence detected in AMG Solver-X momentum , Error Object: #f " when i attempt to solve viscosity as the function of temp?
for the same problem, when viscosity is constant it solves. can you please give suggestions to solve the problem ?

First step would be to post the code here;)

First, be sure that you defined x axis as axisymmetric axis. This is very common in most 2d axisymmetric geometry. check the values for initialization. You must use reasonable values for interest equation. I suggested this supposedly that the UDF is OK.
Good luck
