Features

Input file processing capability

  • Reads input files containing mesh data in the appropriate format (in-depth information about specific format in documentation)

2D Linear elastic analysis

  • Performs 2D linear elastic analysis under plane stress/strain conditions
  • Uses classic four-node bilinear quadrilateral formulation with full integration

GUI for boundary conditions and load definition

  • The GUI eases the process of defining boundary conditions and applied loads with the representation of the meshed geometry.

GUI for post-processing results

  • The GUI for post-processing tasks enables visual analysis of results through the plotting of several data:
    • Displacement fields: U1, U2
    • Stress fields: S1, S2, S12, von Mises
