Domain decomposition for hyperbolic equations

This model shows how to solve an iterative algorithm using domain decomposition techniques.

Coefficient Form PDE u1 (c4) solves for u1
Coefficient Form PDE u2 (c) solves for u2
Coefficient Form PDE v1 (c2) stores u1 into v1
Coefficient Form PDE v2 (c3) stores u2 into v2
Then compute and iterate as follows:

1. Compute Init U
2. In LOOP > Step1 > Values of Variables not solved for : select Solution : Init U , then Compute
3. In LOOP > Step1 > Values of Variables not solved for : select Solution : LOOP, then Compute as many times as necessary to converge

One need to read the comment all to the end: where you remind us that for LOOP on the first iteration one need to set the Values of Dependent Variables, not solver for to point to Init U, then for the second run select LOOP
Nice model :)
