TVD schemes
Can TVD limiters be applied to flux splitting Jacobian matricies F+, F? F = F+ + F

Re: TVD schemes
What's the definition for minmod(x, y, z)?

Re: TVD schemes
minmod=
sign(x)*min(x,y,z) if sign(x)==sign(y)==sign(z) 0.0 otherwise 'sign' will give you a sign of a number 
Re: TVD schemes
And for minmod (1, r) = min(1, r) if r > 0; 0 otherwise
