Hello everyone,

I'm currently conducting ship simulations using CFD, specifically Star CCM+, following initial calculations using potential flow analysis software. In the potential flow analysis, the total resistance is calculated to be 560 kN at a speed of 13.5 knots. However, in the CFD simulations with a half hull model, I'm observing nearly double the resistance, approximately 2,000 kN.

Typically, I achieve reliable results using the Hull Performance plugin, and this case isn't particularly complex. I intended to share the geometry file in .dbs format for reference, but it exceeds 1 MB.

Does anyone have any insights on how to address this issue?
