i got some problem during simulatinga two phase flow in micro T junction..
error come as "divergence detected in AMG solver.pressure correction"
can anybody say me what went wrong:confused:
divergence - AMG
The pressure correction solver doesnt like the constructed matrix - check your solver controls.
1. Reduce relaxation for momentum and pressure and run it.
2. Check your phase change conditions (UDF if you wrote them).
3. Also, try increasing the AMG cycles (min and max cycle limit).
If you are running turbulence - check initial conditions and relaxation for turbu ke and dissipation.
This is a perfect exercise for you to play with the solver controls and get good results.
