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.
