subroutine limiter	(	real(rtype), dimension(:,:), intent(in)	umin,
		real(rtype), dimension(:,:), intent(in)	umax
	)

Parameters

umin	minimum of U_i and of min_j U_j (U = rho, u, v, p)
umax	maximum of U_i and of max_j U_j (U = rho, u, v, p)

real(rtype) function limiter::venkat	(	real(rtype)	d2,
		real(rtype)	d1min,
		real(rtype)	d1max,
		real(rtype)	eps2
	)

Parameters

d2	change of value to be limited (gradient * distance)
d1min	min(U_i, U_j) - U_i
d1max	max(U_i, U_j) - U_i
eps2	threshold value

Returns

limiter value
