A F E M - FEM Code


Status

Overview

Final version is planned before year 2100. There are some functional parts (solver, pieces of postprocessor) and many non-functional ones.

More than 45 000 lines of source code have been written.

Finite elements

All elements are 2D now (3D elements are planned).

  1. link,
  2. plane element (three nodes),
  3. isoparametric plane (four nodes),
  4. isoparametric plane (eight nodes),
  5. isoparametric plane (nine nodes),
  6. plane element (three nodes) with support of data for nonlinear computations,
  7. isoparametric plane (four nodes) with support of data for nonlinear computations,
  8. isoparametric plane (eight nodes) with support of data for nonlinear computations,
  9. isoparametric plane (nine nodes) with support of data for nonlinear computations,
  10. beam (two nodes).

Linear equation system solvers

Gauss - Seidel and Conjugate Gradient methods can be used.

Support for nonlinear solution

Newton-Raphson and Arc-Lenght methods have been written (ALM has some limitations).

What is missing

There is no (usable) interactive preprocessor and many things (result plotting for some elements, version controlling, better meshing tool) are unfinished.
