Problem in contact force - Explicit Dynamics
I'm modeling an experiment experience in Explicit Dynamics. I modeled a concrete bridge deck with elastomeric bearings. The impact between the abutment and deck was modeled with body interaction. When a see the graphs of Contact force, i see positive force and i don't understand why.
Then a put 8 springs to try to measure de contact force, but a i have problems:
- Could not transfer loads and constrains to the solver
- Cannot apply multiple constraints to rigid part
- Failed to submit solve job. See Solution Information, which may contain more details.
- One or more parts were found to be unmodified so smart update.
The real problem is that a can't measure de impact force (Contact force) properly.
