Ali Heydari

you should define UDF for time variable speed.

Ahmed S. Mansour

Thanks sir, do you know how to do this?

Thanks

Tariq Ullah

Ahmed S. Mansour hello sir, i am doing the same thing, have you got any UDF for variable speed?

Hello dear Tariq Ullah Yes I used the dynamic mesh technique using 6 DOF solver. I uploaded this tutorial. Check it out please. Danke!
