Detailed Description

Mesh motion solver that uses a medial axis algorithm to work out a fraction between the (nearest point on a) moving surface and the (nearest point on a) fixed surface.

This fraction is then used to scale the motion. Use

  • fixedValue on all moving patches
  • zeroFixedValue on stationary patches
  • slip on all slipping patches Note that the fixedValue boundary conditions might be changed by this solver to enforce consistency and a valid resulting mesh.
