Solver Mass entity management
A new option in the Appearance Preferences allows you to display the graphics on nodal masses defined inside the *ELEMENT_MASS Solvermass entity.
With the graphics activated, you are now able to manage the individual nodal masses. For example:
  • Organize a selection of nodal masses into another Solvermass entity of type *ELEMENT_MASS.
  • Select and edit any nodal mass and modify the mass value.
  • Select and delete any nodal masses defined into a Solvermass entity of type *ELEMENT_MASS.

Resolved Issues

  • Export Solver Deck feature, when selecting a material linked to multiple MAT_ADD cards: all linked MAT_ADD keywords are now exported with the selected material.
  • Removed Title checkbox in *DEFINE_FUNCTION keyword Entity Editor.
