Shipflow: Virtual Towing tank

[sobo]

Hi

I am currently developing a new hull form for a catamaran boat using Maxsurf.
Now is the time for me to verify my result obtain in Hullspeed.
Therefore, I am trying to use Virtual Towing Tank instead of develop a model to be run on a real Towing Tank.

I heard that Shipflow can do it. But, I cannot find it in the manual.
Does anyone here expert in Shipflow?
I hope someone can help me solving this problem.

Thanks

I'm not exactly sure what you mean by using a "virtual towing tank", but there has been some close investigations of Shipflow's predictions.
For example, see:
Sam Abbott,
"An investigation into shallow water effects on high speed craft"
Faculty of Maritime Transport and Engineering,
Australian Maritime College,
Oct. 1998.

Abbott used Shipflow to predict the resistance and squat of a (modified) Series 64 monohull and catamaran.
He had great difficulties in getting sensible converged results, and was advised by Shipflow that the large transom stern was the cause.
Eventually, he had to run Shipflow in "linear" mode to avoid the problem.

Good luck!
Leo.
