New Physics Solver "ICA Stiff Solver" (USER)

IC.IDO 12.1 introduces the next generation of physics solver. The new solver focuses on improvements of performance and stability in general, but also puts focus on Elastic1D-Elastic1D and Elastic1D-Rigid contact situations resulting in improved collision handling and more realistic deformation of the Elastic1D shape. The new Physics Solver ‘ICA Stiff Solver’ is the new default solver in 12.1. This article explains about the main differences and improvements compared to the earlier solver, and gives hints for how to work with the new solver for achieving best user experience.
