Hi,
Modeling 2D pipe flow with some kind of flap in the middle of the tube.
I am experimenting with Moving Mesh vs. Rotating Machinery. I believe I'd like to have the control Moving Mesh appears to allow (the kind of mesh smoothing), but Rotating Machinery is the only that already includes a specific interface for rotation. If it is necessary to use Moving Mesh, how can I prescribe rotation only using dx, dy ? Can I make dx a function of the distance to a certain point? (effectively creating a rotation of some sort)
When using Rotating Machinery, the mesh doesn't look pretty (see attached image, with Rotating Domain on the left, identity pair being the line in the middle). The mesh doesn't line up properly, is that a problem? I added boundary layers and the solution improved (no longer an abrupt change of regime), but how much should I trust this?
Thank you all for input
