Welcome brother . Following models i have used for physical model setup in star CCM plus-
Implicit Unsteady time group
Eulerian Multiphase Material group
Volume of Fluid (VOF) Multiphase Modelgroup
Turbulent viscous regime
and k-epsilon turbulence model
optional models were Gravity,Cell Quality Remediation, and VOF Waves
I have followed the step by step tutorial provided with the software and previously i messed up with dynamic fluid body interaction for calculating sink and trim. This time i have excluded the sink and trim calculation and rather opting for only resistance calculation.
