Arbitrary Lagrange/Eulerian moving mesh*

FlexPDE 7 allows the definition of mesh-moving equations*, and applies an Arbitrary Lagrange/Eulerian (ALE) formulation. This allows several optional behaviors:

In any case, FlexPDE automatically corrects the PDE system to represent the motion of the mesh.

The problem shown here computes the motion of a gas in a compressor cylinder.
