A 6x5 element mesh with 42 nodes & 2009 grid pts is subjected to a plane wave along the LH edge. Element 3 represents an infarct with SACs. The wave spreads around the infarct and by stretching the infarct causes the SAC to initiate a new wave. Note that the key parameters are:
SAC conductance is -20
Threshold for SAC now set to lambda=1.1
Time constant scaling is 7 in infarct, 7 elsewhere
Time constant during repolaristation is 0.066ms
No Ca release in infarct
No 'fem update grid metric deformed'
In mech.ipacti To=10kPa and Ca_max=1
Time step dt=0.002ms
