Observed occasional numerical stability problems in some cases:

  • long range and complicated bathymetry
  • complicated sound speed profile with :smooth interpolation

In most cases these are resolved by using a lower tolerance or a stiffer solver, but not always. For now :smooth interpolation on SSP should be considered "broken".

The problem with :smooth SSP seems to do with q becoming negative. Perhaps the curvature in SSP is leading to caustics that are not dealt with correctly. Related to #6 ?
