Energy Weight Function

Energy Weight Function = {GALERKIN | SUPG} <float>

Description / Usage

This card specifies the weight function to be used on the weighted residual of the energy equations. For high Peclet number cases, you may want to use a Petrov- Galerkin formulation rather than a Galerkin formulation. Definitions of the input parameters are as follows:

GALERKIN	Name of the model for the weight functions for a full Galerkin formulation. This is the default when this card is absent. <float> - the value of the weight function, a number between 0. and 1.; a value of 0. corresponds to GALERKIN.
SUPG	Name of the model for the weight functions for a streamwise upwinded Petrov-Galerkin formulation. <float> - the value of the weight function, a number between 0. and 1.; a value of 1. corresponds to a full SUPG.

Examples

The following is a sample input card:

Energy Weight Function = GALERKIN 0.0

Technical Discussion

The SUPG weighting is applied only to the advective term in the Energy conservation equation and Jacobian assembly.
