Minimum pressure:

*Material, ...
*Min pressure
<minimum pressure>

This parameter is used to correct small effective pressures in case barotropic constitutive models are used. Set this pressure to the minimum allowed pressure (mechanical sign convention, i.e. give a negative value). This parameter should be set for the following materials:

Model	Reference
Hypoplasticity + Intergranular Strain	Hypoplasticity + IGS
Hypoplasticity + Intergranular Strain Anisotropy	Hypoplasticity + ISA
Sanisand	Sanisand
Modified Cam Clay	Modified Cam Clay
Anisotropic Viscous ISA	AVISA
High Cycle Accumulation model for sand (coupled with Hypoplasticity + Intergranular Strain or Sanisand)	HCA-Sand
High Cycle Accumulation model for clay	HCA-Clay
