+The descending slab will cause some numerical instability in the temperature
+ solver.
+ To reduce the numerical instability, you will use a smaller time step size
+ (0.75 of the maximum time step size for stable solution).
+ The change in temperature maximum will also be monitored.
+ If the maximum temperature increases too much (> 5%) between time steps,
+ the temperature solver will rerun with half time-step size.
