Rigid wall contact

1. Flexible Body - Rigid Wall


2. Rigid Body - Rigid Wall

εr . . . penaltyfactor rigid body


εs . . . penaltyfactor rigid wall

Spring forces: Fi = εs · δi

Options of the stonewalls:

  • initial mass and velocity
  • fixed in space
  • velocity or displacement specified by a load curve

A stonewall may extent to infinity or the extent may be finite.


  • frictionless sliding after contact
  • no sliding after contact
  • coulomb friction Fc = µ · FN
  • orthotropic frictional coe cients by defining fixed vectors
  • orthotropic frictional coe cients by defining nodes
