cflSpeed()

Real Wavespeeds::cflSpeed ( Real v0, Real v1 ) const

inline

Low-level helper function.

Computes the correct combination of speeds to determine the CFL limits.

It should be in-plane, but we use the complete wave speeds from calculateWaveSpeed??().

At the moment it computes the geometric mean of both bulk velocity components and takes the maximum of that plus either the magnetosonic or the whistler speed.
