I'm performing a self propulsion test, using body force propeller method. I have performed resistance for bare hull it came around - 55 tons. Now i need to estimate the thrust & wake fraction for which I'm referring the tutorial guide. I have input all the parameters of virtual disk as per the virtual disk co-ordinate system. (attached image)
I have run the simulation, it is giving a thrust of 71 tons, but eventually drag is decreasing with increase of speed. With this thrust I can estimate thrust deduction factor, but how do I know my velocity of advance Va & wake fraction.

Please help me solve this problem.
Thank you.
