Dear All

I would to make a 3D moving mesh simulation ([beginner]) for my master thesis.
I have created already the model in ICEM CFD now. I need to simulate 3D box (chamber filled with air pressure) with a cantilever which opens up to let the air out through a small hole into the atmosphere from a closed position. The cantilever max deflection is <1 degree.

I need to know how to do the moving mesh. Would someone be kind enough to give me an idea where to start with etc?

Unfortunately, I am under time constraints; can only spend 2-3 weeks on this. Would be great if someone can guide in the right direction.
Many thanks

Moving mesh is done in Fluent, not in ICEMCFD

Thanks Here they talk about a moving mesh in ICEM CFD...

Will modify the question.

The meshing is no problem...

But the mesh would just be a static mesh...

By dynamic, do you mean that the flow is dynamic around a static airfoil or do you mean that the flow causes the airfoil to flutter? Would you be looking at one way FSI then and also need a structural mesh?

The latter would probably require some sort of mesh morphing for small changes.

If you mean to look at large changes (such as a control surface rotating), then you could use ICEM CFD scripting to block it once and then adjust the angle in the script. Another option would be to put the airfoil in a circle that you could then rotate the static mesh around the centroid.

For solver directed mesh morphing, I recommend you go to the solver forum and ask that question there. For a while, we did have a mesh morpher in ICEM CFD (MOM3D or Optimesh) but we eventually decided that mesh morphing was most efficiently done in the solver and we should focus on providing only the initial mesh.

Maybe someone else in this forum will have some good info for you...
