Bonding and Contact Architecture

Several enhancements to the bonding and contact architecture improve the overall performance and accuracy of the simulations.

  • Removal of duplicate degrees of freedom in bonding and contact constraint equations
  • Reduced bonding and contact constraint equations
  • Measurement of bonding and contact strains in units of distance rather than volume
  • Improved calculation for the constraint area
  • Optimization of unitless parameter associated to bonding and contact penalty stiffness
  • Elimination of unnecessary function calls for small tasks within the contact search code

Performance improvements based on these enhancements are more noticeable for simulations that run with the FFEPlus iterative solver and have a large percentage of nodes participating in bonded and contact interactions.
