Dynamic mesh

Rowing · May 17, 2011, 08:25

Hello

I'm a fourth year student doing my skripsie on the design of a rowing tank.

I want to model the blade through the water as a moving mesh.

How is this done? Do I have to write a UDF for this?

I know the frequency of the rowers, the speed of the blade and locations were it should enter and leave the fluid.

Any help??

Thank you

Hi,
for these kinds of problems, moving reference frames is much easier. Check it out in user manual.

Thanks for the reply!

I'm just wondering how one would implement that? At the moment I have the water body and blade as two different parts in design modeller.

If I select moving reference frame for the blade, how would I get it to appear after the first run again? With other words, how do I implement the frequency?

Can moving reference frames by applied for linear motion?

Thank you very much

Hi,
you can set constant linear and rotational speed for reference frame, check also MRF (multiple reference frames)
