Computation of central artificial dissipation with preconditioning. More...

Functions/Subroutines
subroutine	dissipcentralprec (beta, dp)
	Computes artificial dissipation as a blend of 2nd- and 4th-order central differences. This corresponds to the JST scheme. The dissipation terms are multiplied by a preconditioning matrix for low Mach numbers (see Eq. (9.52)). More...
