EQ = eddy_visc {Galerkin_wt} eddy_nu {Interpol_fnc} <float1> <float2> <float3> <float4> <float5>

Description / Usage#

This card provides information for solving a differential equation for Spalart Allmaras turbulence model Definitions of the input parameters are defined below. Note that <float1> through <float5> define the constant multipliers in front of each type of term in the equation. The Galerkin weight and the interpolation function must be the same for the code to work properly.


Name of the equation to be solved


Two-character value that defines the type of weighting function for this equation, where: Q1-Linear Q2-Quadratic


Name of the variable associated with this equation


Two-character value that defines the interpolation function used to represent the variable eddy_nu, where: Q1-Linear Q2-Quadratic


Multiplier on the mass term


Multiplier on the advective term


Multiplier on the boundary terms


Multiplier on the diffusion terms


Multiplier on the source term

Note: These multipliers are intended to provide a means of activating or deactivating terms of an equation, and hence should be set to zero or one. If a multiplier is zero, the section of code that evaluates the corresponding term will be skipped.


The following is a sample card that uses quadratic continuous interpolation for the species equation and turns on all the term multipliers:

EQ = eddy_visc Q2 eddy_nu Q2 1. 1. 1. 1. 1.
