Max(gamma) increases slowly
 
Hi all,
I am using a modified interFoam solver to simulate the filling process of polymer melt, which is a non-isothermal, non-newtonian, incompressible and two phase flow.

In my simulation test,the value of Max(gamma) increases slowly as the calculation moving forward:
Min(gamma) = -1.16383e-34 Max(gamma) = 1.00001
Min(gamma) = -9.90024e-35 Max(gamma) = 1.00002
Min(gamma) = -2.39511e-33 Max(gamma) = 1.00003
...
Min(gamma) = -1.33329e-20 Max(gamma) = 1.00935
Min(gamma) = -2.30943e-20 Max(gamma) = 1.00943
...
Finally, Max(gamma) is much bigger than 1.

I would appreciate if someone can help me on this.

Best Regards
JItao

did you do a meshsensitivity-study??

I used PointWise to generate a three-dimensional hybrid mesh. I have tried different mesh densities. It made no sence.

Thanks for your reply. I'll pay more attention to it.
