Subcycling (Mixed Time Integration)
Elements are sorted based on their step size into groups, whose step size is some even multiple of the smallest element step size.
Elements are sorted three times:
- By element number in ascending order
- By material number for large vector blocks
- By connectivity to insure disjointness for right hand side vectorization.
- Large speed-up for problems with di erences in element size.
- Allows local mesh refinement without penalty.
