Hello Foamers
Thought is it better to start a new thread for the question.


Target of the CFD simulation - Evaluation of multi-hull ship resistance based on DTCHull. Using version 5.x. Using symmetryPlane feature.

The simulation type is laminar due to low Reynolds number (model scale simulation to compare with model scale experiment results). turbulenceProperties file is changed accordingly. In post-processing of forces, pressure and viscous forces are obtained. When obtaining the Cf (coefficient of viscous force) value, wetted surface area of half hull needs to be used (as per my understanding). However, if we use half hull wetted surface area, the viscous coefficient is not correct when compared with Blasius solution. But if we consider the full hull wetted surface area, it matches with the Blasius equation.

I am really confused with the reason for it. Therefore, now considering if the modeling of simulation (setup conditions) are correct or not.

Please help with some insights especially if you have used DTCHull tutorial.

Thanks in advance.
