I have question : When automatic constraints will be improved I mean not repeating the same surface as master in many constraints ? in complex assemblies it is a real problem and it takes a lot of time to swap/merge this constraints and many constraints are indicated as unresolved
Some info here: Unresolved shell - #2 by Matej
But even in Abaqus you have to use the Find Contact Pairs tool carefully and in most actual cases it’s necessary to adjust the tie definitions manually.
It is not easy to automatically determine and resolve all constraints. Sometimes, a loop is created where no solution exists in some cases. If you have an idea of how to solve this problem, a solution would be more than welcome.
