HELP: unsteady solving of Moving body in fluid
If the body is moving, then the grid attached on it is moving, too. But I don't use refference on the body.
For time t, assuming I get the flow field at t+dt and velocity of the body. Then I move the body and grid. But how can I get those flow state on the new grid?
Re: HELP: unsteady solving of Moving body in fluid
There are two ways:
1. Decoupled. solve flowfield of t+dt using grid at t.
Then move the body explicitly.
2. Iterative. The above two procedures are repeated
untill a certain convergence is obtained. I think you need do the second way.
