fem2d

Collection of programs developed to perform various engineering analyses on structures using the finite element technique.

Features

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”
