Adds nonlinear mechanical material model. Currently only plasticity with simple hardening is available.


  1. To define nonlinear mechanical material model do the following:
  2. To edit an existing MaterialFluid object:
    • Click it in the Tree view.
    • Select the material model (currently only simple hardening is available).
    • Define yield points (stress vs plastic strain). The first point must have a zero plastic strain specified. Currently only 3 yield points can be defined.
