Summary0004102: Contact constraint feature intensive
DescriptionIn the FEM workbench the contact constraint is feature-tree intensive. for EVERY set of surfaces a new feature has to be created.
I have created a example where two bodies have contact by 3 surfaces all in the same plane. I have to create 3 contact constraints.
I would give two ideas
  1. give 1 master and serval slaves (or reverse: 1 slave and serval masters) this create automatically a set of master and slave for every set inside the feature
  2. give equal set of masters and slaves and create a master-slave for each index in the list. (just master[0] and [slave[0] to master[N] and slave[N] no crossrelations...)
Steps To ReproduceSee example
