The tool has been written purely in HTML and JavaScripts, therefore:

  • no installation required;
  • running wholly in the client's machine;
  • working online, and even offline after loaded.

For two-dimensional bar problems, structures can be:

  • truss;
  • beam;
  • frame.

For two-dimensional elasticity problems, triangle elements are used, and can be:

  • plane stress;
  • plane strain.

Interim results can be shown for the purpose of learning.
