[FLASH-USERS] upwind TVD

[Ryan Farber]

Hi Maksim,

I think you still have a choice between the various slope limiters in
conjunction with upwind TVD (but cf. the user manual). The hybrid slope
limiter is nicer for accuracy but I think minmod is the most diffusive so
the best for numerical stability.

Best,
