We then turn our attention specifically to those models for which the exact distribution of microstates in the steady state can be expressed in a matrix-product form. In addition to a gentle introduction to this matrix-product approach, how it works and how it relates to similar constructions ...
Implicit finite element algorithmsusually need to repeatedly solve large-scale sparse linear systems with tens or hundreds of millions of degrees of freedom. The sparse linear solver is a critical part of AcuSolve and is the most time-consuming part forsteady-state simulations, taking u...
摘要: This report documents the theory and usage of the Program EAGLE- Flow Solver; a multiblock implicit, steady-state Euler algorithm used for the aerodynamic analysis of advanced arbitrarily shaped airframe configurations in freestream and interference flowfields.关键词:...
Two conservative genuinely multidimensional upwind schemes are presented which have been adapted from ux balance distribution methods recently proposed for the approximation of steady state solutions of the Euler equations on unstructured triangular grids. A method for dealing with source terms, such as ...
