Rotating patch not rotating?
I am trying to implement a rotational motion on a patch in OF1.6.x so that the patch rotates for 0.001 radian per time step. The rotation was implemented using a rotational tensor, and the points on the patch moved using the following algorithm:
However, after running the solver for a couple of time steps (~1,000) the patch and the grid points around it hardly moved as oppose of turning the prescribed 1 radian (~58 degrees). I'm wondering if I'm doing anything wrong or has used the wrong expression for implementing the displacement fields. Any help will be greatly appreciated.
