Contact Icon toggle settings define surface interactions in simulations, crucial for modeling friction, separation, and penetration. Please click here for more information . By default, Contact Required is set to No and must be enabled for defining contact behaviors. Once enabled:

Master and Slave Surfaces: Assign the stiffer or larger body as the masterIcon toggle, and the softer or smaller body as the slave Icon toggle for numerical stability.

Normal Contact: Governs interactions in the normal direction using methods like the penalty approach. Options include:

  • Separation: Allows or restricts surfaces from separating.

  • Penalty Stiffness: Defines the stiffness parameter for penetration.

Tangential Contact: Controls friction behavior with three models available:

  • Frictionless: Assumes no resistance in the tangential direction.

  • Mohr-Coulomb (MC): Models tangential resistance using coefficients like tan δ and cohesion (default: 0 kN/m²).

  • Hypoplastic: Advanced model for complex geotechnical applications.

Contact Options: Include settings for clearance, displacement checks, and distance validations, offering enhanced accuracy and control.
