The spiral wave trains begin to modulate and eventually the spiral
breaks in the far-field region. Linear stability computations as
these parameter values show that the spiral is linearly unstable.
Model Parameters for simulation:
Note: For these parameters the spiral breakup is very sensitive to details of the simulation. Small changes in numerical parameter may result in breakup closer or further from the spiral center.
