How to move mesh with oscillating bubble?

Kristina · July 27, 2011, 09:56

Hi,

I'm new in OpenFoam and trying to solve a problem with an free oscillating bubble. In my Case there is no flow just a deformed bubble which is oscillating. But as soon the self damping begins the bubble starts to slip out of my domain.

Now I'm thinking about to move my mesh with the slipping bubble but don't know how to create this.

Is InterDyMFoam the right solver for my problem or shall I use moveDynamicMesh?
In both solvers I should to create a file called or motionU or pointDisplacement-but i don't find out how to modify them.

Can anyone help me?
I'm thankful for any help!

Kristina

Maybe solid body motion could be right for you.

Thanks for your answer
I'm now trying gen6DoF with InterDyMFoam...maybe it will work
