Sliding Mesh

ashkan · February 4, 2014, 22:02

Hi,
I have a problem and appreciate some comments/help on how to resolve it.

The problem I am working on is a large submerged (it can also undergo surface piercing) body that undergoes 6 degree of motion due to incident waves (though, the main motions are heave, pitch and surge). The simulation is working fine by using "displacementLaplacian". However, I have issues when dealing with large waves due to large pitch motion.

I am interested in using the sliding mesh interface or AMI solvers. I could not find a step-by-step explanation on how to set up a case using sliding mesh. Can anyone please give me some advice on how to do this?

In general I use blockMesh for the tank mesh and then snappyHexMesh with the STL file of my submerged body.

Any help is appreciated.
Many thanks guys.

look at the propeller test case in pimpleDyMFoam, it uses AMI
