************************** **Energy Weight Function** ************************** :: Energy Weight Function = {GALERKIN | SUPG} ----------------------- **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. | | | | | | * - 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. | | | | | | * - 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. -------------- **References** -------------- No References.
