You should only provide a pointMotionU file with oscillatingFixedValue i.e. for your moving wall. (The cellMotionU is derived from that, you could delete that file).....Just try this. Additionally,...

The subsets should be decomposed as well. Somewhere on this message board their lives a decomposeParWithSets, or something like that. That utility should do the job, for me it worked fine....

At my department people are also working with a cfd code which uses radial basis functions to update the mesh point positions in time. Those people are very happy with the...

Allright, when I decrease the timestep 4 times, the mesh Co number gets around 0.5 and the mesh moves a lot better using linear or quadratic. Constant diffusion leads to a lot of skewness near the...

Sorry to bother you.
With 'they do not work at all' I mean that using those distance-based methods the mesh collapses just after maximal amplitude. For the moving mesh testing I used dt=0.005....

Hi again,
Does anyone know how to use subsets of meshes in order to only move the subset directly around the moving body. That probably will reduce the computation time considerably.
