Make stasis constraint compatible with restart and adaptive mesh refi…

[AmishgaAlphonius]

Description of the problem

• The recently implemented vof stasis constraint (Implement temperature-dependant solid domain contraints in VOF #1048) was not compatible with adaptive mesh refinements and checkpointing system. When refining the mesh or when restarting a simulation, the filtered phase fraction was reinitialized, but not filled with the appropriate values.

Description of the solution

• The apply_phase_filter() function was added to post_mesh_adaptation() and read_checkpoint() functions.

How Has This Been Tested?

• The stasis constraint was tested using the 2D LPBF benchmark :
  • with restart and mesh adaptation;
  • without restart and with mesh adaptation, and;
  • with restart and without mesh adaptation.
