Description

Currently time windowing is done using the same velocity basis for every time window.
A possible next step is to also do time windowing on the velocity basis, which should lead to smaller EQP systems and better performance in general.

Research direction

Start by locating the Nonlinear Elastic example and its existing time-windowing implementation. Determine how the velocity basis is shared across time windows, then define and validate window-specific bases with reduced EQP system sizes and improved performance as the completion criteria.
