I am having trouble with boundaries in a 2d analysis, I have two bodies, one inside the other experiencing forces. I can make it work with several friction boundary conditions on pairs of edges, however rather than identifying which faces are/will be touching I would like to apply one boundary condition to all the boundaries as follows:
Code: Select all
Boundary Condition 2
Target Boundaries (8) = 105 106 107 108 109 110 111 112
Mortar BC = 3
Friction Contact = Logical True
Static Friction Coefficient = Real 0.9
Dynamic Friction Coefficient = Real 0.8
Contact Depth Offset Initial = Real 1.0e-4
Plane Projector = Logical True
Galerkin Projector = Logical True
Normal-Tangential Displacement = Logical True
Initial Contact Velocity = Real 0
End
Boundary Condition 3
Target Boundaries (4) = 113 114 115 116
Normal-Tangential Displacement = Logical True
End
The MultipleBoundaryConditions.sif file contains the setup that works, and the SingleBoundaryConditions.sif file contains the setup I would like to work.
Thanks very much in advance for any guidance you can give.

Krishan
