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.

eddy_visc

Name of the equation to be solved

{Galerkin_wt}

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

eddy_nu

Name of the variable associated with this equation

{Interpol_fnc}

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

<float1>

Multiplier on the mass term

<float2>

Multiplier on the advective term

<float3>

Multiplier on the boundary terms

<float4>

Multiplier on the diffusion terms

<float5>

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.

Examples

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.
