Hi,
I am trying to mesh a 50 M ship running at high speeds going upto 33 knots. The issue is that to get the Yplus between 30-300 for KWSST model. The mesh size would go above 25 mill cells with snappyHexMesh which is not feasible for me to run on my machines. I am using the same meshing tactic employed in the DTC Hull tutorial with toposetDict based refinement. I am doing a steady state analysis using LTSInterfoam. Is there a way where I can reduce the mesh size drastically to about 8-10 mill and still keep my yplus in required range? Is there any wall function that handles larger Yplus values? |
