Description

Performs a step of Euler implicit for II order systems using the Anitescu/Stewart/Trinkle single-iteration method, that is a bit like an implicit Euler where one performs only the first Newton corrector iteration.

If using an underlying CCP complementarity solver, this is the typical Anitescu stabilized timestepper for DVIs.
