VOF setting for ship's hull study
Hi everyone, I'm trying to simulate the flow around ship and I use multiphase flow VOF in FLUENT for analize this type of problem. I use a fully hexa mesh with high qualty ( determinant 3x3 from 0.6 to 1) generated with ICEM CFD
My setting is Reynolds Stress Model, VOF Implicit with open channell formulation, seady state I've tryied a k-w SST viscous model too.
I have some problem about this simulation:
1) My simulation diverge with k-w SST, and with the RSM i need to decrease more the under relaxation factor (0.15 max)
2) If i try to simulate a case with y+=50 or less, after 200 iteration the simulation diverge.
What can i do?? What type of setting is required??
If someone have any information or solution fot this type of problem please send me at my email : firstname.lastname@example.org
Thank's for attention.
