ADVC(ADVENTURECluster) Contact Parameters

  • Contact Type: Used to select the contact slip property either as Small Sliding / Finite Sliding / Tying.
  • Adjust: Used to specify the adjust value which defines the distance by which slave nodes will be moved on to the master surface.
  • Adjust To Clearance: Used for avoiding contact elements collapse when moving their nodes using the adjust value.
  • Adjust To Interference: Used for avoiding contact elements collapse when moving their nodes using the interference value. It is applicable only for "Finite Sliding" contact type.
  • Auto Shrink: Used to control the penetration of contact surfaces when interference is defined.
  • Thickness: Used to correct the amount of gap between contact surfaces by taking shell element and membrane element thickness into consideration.
  • Initial State: Used to define the initial contact state. Auto/Open/Close contact states can be defined.
  • Initial State Tolerance: Used to define the tolerance which helps in automatic determination of the initial contact state.
  • Estimate Impact Time: Used to output the Impact/Collision time in a dynamic analysis.
  • Search Gap: Used to specify the search distance for the contact surface in the normal direction.
  • Search Depth: Used to specify the search distance for the contact surface in the normal direction.
  • Search Width: Used to specify the search range in the in-plane direction of the contact surface.
  • Search Angle: Used to specify the angle between outbound normal vector of a master surface and inbound normal vector of a slave surface.
  • Clearance: Used to specify the clearance between the master and slave surfaces. A positive value represents the clearance whereas a negative value represents penetration.
  • Interference: Used to specify the interference between the master and slave surfaces. A positive value indicates that the master surface moved for the given value in the normal direction into the slave surface.
  • Penalty Scale Factor: Penalty factor is given by multiplying stiffness of a region connected with contact constraint by penalty scale factor.
  • Critical Penetration: Used to control the convergence calculation if the peak value of the penetration exceeds the given value. The convergence calculation is re-started with smaller increment value.
