PERMAS-CAX Extended Contact Analysis with PERMAS
This module has been designed to provide new contact solution algorithms for large contact models (more than 10,000 contact node pairs) in order to essentially
accelerate contact analysis runs again (by a factor of 3 and beyond). The module is used as an add-on to module PERMAS-CA (see preceding section).
The functionality comprises the following features:
- High performance iterative solution algorithms to accelerate standard contact analysis with normal and frictional contact.
- An additional very stable iteration method for critical slip-stick problems (when all contacts get into sliding state, see figure).
