SPARSEMETHOD

Description Type Default

Specifies the VSS sparse direct solver matrix reordering method:

  • HEAT - Used for one degree of freedom per node models such as in heat transfer solutions.
  • SHELL - Used for six degree of freedom per node models such as in structural models with shell and line element types.
  • SOLID - Used for three degree of freedom per node models such as in structural models with only solid elements.
  • SOLVER - Directs the solver to determine the best reordering method based on the input stiffness matrix.
  • AUTO - The program picks the best method based on the element types and solution selected in the model.

Additional reordering options can be selected using the RESEQGRIDMETHOD directive.
