Interesting problem. Are the oscillations self-induced or operator driven?
My work is on snow, ice and rain simulations using two-fluid formulations. I've done some work in aircraft icing as well.

Hi Dan,
The extrude/cut process involves using extrudeMesh (which doesn't cut) first and then splitMesh (which cuts) to make the internal boundary external. splitMesh is a bit tricky to use. Will...

Hi Daniel,
I tried once to make a 2D mesh with sHM but got more than one cell in the z direction. I think this is due to the fact that sHM divides whatever you have initially in blockMesh in the z...
