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.
Friction:
- 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
