Simulation of ice field interaction with vertical structure (ALE)

      Hello everyone.

      I'm trying to perform simulation of ice field interaction with offshore vertical. To create buoyancy forces I perform ALE modelling. Ice field is not moving with displacement restriction (Lagrange solid body). Only vertical structure is moving as rigid body with low speed (0,01 m/s) (Lagrange splid body). Ice field finite elements should be removed after critical damage (Drucker-Prager plasticity model is considered). I'm not intersted of behavior of water at all, it is created only to provide buoyancy forces for ice field.

      i use an simple model of water but the settings works for most of the cases

      1) you need just one*CONSTRAINED_LAGRANGE_IN_SOLID card between the sider and ice
      2) you can use automatic _surface_to_surface
      3) ALE works on the basis of cells, smaller the cell better the resolution be
      cheers, Ram
