  • two-dimensional plane or axisymmetric problems
  • cartesian or polar coordinate systems
  • uses Rexx macro language
  • linear and quadratic isoparametric elements available
  • no limit on number of nodes, elements, materials, or boundary conditions (only limited by memory)
  • no need to specify problem size (determined at run time)
  • group (part) definition/manipulation
  • simple draw commands for symbols, lines, and labels
  • Dirichlet (constraint) or Neumann (flux), point or distributed boundary conditions
  • globally or locally referenced material properties
  • laminated materials
  • definable post-processing functions
  • solution and result superposition
  • command aliases for customized uses
  • linear and nonlinear (geometric) solvers provided
  • solvers use a symmetric banded matrix storage format
  • solvers can handle coupled analyses
  • node order optimizer for bandwidth reduction
  • node equivalence code for part “welding”
