β¦ Synopsis
In this work, the MacCormack methodology is extended to implicit compact differencing schemes. A prefactorization method is developed which splits the implicit matrix into two independent upper and lower matrices which are easier to invert. Using this method, a new class of high-order accurate compact MacCormack-type schemes is derived. Two fourth-order schemes are described, and results are shown for three linear and nonlinear CAA benchmark problems.

Implicit, high-order schemes are developed for time-accurate numerical solutions of hyperbolic equation systems. High-order spatial accuracy for the implicit operators is obtained at no additional computing cost by performing compact differentiation. The resulting alternating direction implicit and
## Abstract This work investigates a highβorder numerical method which is suitable for performing largeβeddy simulations, particularly those containing wallβbounded regions which are considered on stretched curvilinear meshes. Spatial derivatives are represented by a sixthβorder compact approximati
