  • Except for calculations in 2D, for all above boundary conditions it is important that they act on a face or body. Boundary conditions for 3D set to lines or vertices are not recognized by the Elmer solver.
  • Since Pressure load can only be set to faces, pressure loads cannot be used for calculations in 2D.
  • If there is no Pressure load set, Initial pressure condition will only be taken into account if DataGradp Discretization is set to true.
