Hi

I am facing divergence problem during a mould filling simulation using multi-phase Eularian model. When I am trying to access the pressure [C_P(c,t)] of the secondary phase, it shows the divergence. I have used a udf (DEFINE_PROPERTY) for viscosity change with pressure value of the secondary phase. The same udf is working with a simpler geometry but not with my actual geometry. The mesh quality of the geometry is
Minimum Orthogonal Quality = 7.56955e-01
Maximum Aspect Ratio = 1.69498e+01 (about 10% of the total elements)

If I take the pressure value as a constant then it works fine with the current geometry.

Please give me your suggestions.
Thanks a lot.
