    • n roach A common cyprinoid fish of Europe, Leuciscus rutilus. It inhabits the lakes, ponds, and slow-running rivers of England and of the south of Scotland, and is common in most other rivers in temperate parts of Europe. Its color is a grayish-green, the abdomen being silvery-white, and the fins reddish. It is gregarious, and the shoals are often large. Its average weight is under a pound, and, though a favorite with anglers, it is not much esteemed for the table.

Considerable work on verification and validation of simulations has been done in the field of computational fluid dynamics (CFD), and in the CFD literature the terms verification and validation have precise, technical meanings (AIAA 1998; Roache 1998a,b).
On Validating an Astrophysical Simulation Code
Roache goes on to point out that in a meaningful sense, a “code” cannot be validated, but only a calculation or range of calculations can be validated.
On Validating an Astrophysical Simulation Code
Roache (1998a) notes that “inadequate iterative convergence will pollute grid convergence results” and that the issue of iterative convergence can blur the distinction between verifying a code and verifying a calculation because iterative tuning parameters can be problem dependent.
On Validating an Astrophysical Simulation Code
This is the step Roache refers to as defining “precisely what partial differential equations are being solved,” though the process may require a larger scope.
On Validating an Astrophysical Simulation Code
As Roache (1998a) mentions, a thoroughly verified incompressible fluid dynamics code will produce invalid results when applied to a problem in which compressibility of the fluid affects the dynamics.
On Validating an Astrophysical Simulation Code
Other app roaches focus on the manual or automated simulation against a formal specification ( see for a description of tools that employ these two approaches).
