33.4.32 UDS Diffusion Coefficients Dialog Box

The UDS Diffusion Coefficients dialog box (opened by selecting uds and clicking on the Edit... button next to UDS Diffusivity in the Create/Edit Materials dialog box) allows you to define the diffusion coefficients for your user-defined scalar transport equations.

(Note that the UDS Diffusion Coefficients dialog box is a modal dialog box, which means that you must tend to it immediately before continuing the property definitions.)

Controls

User Defined Scalar Di   contains a selectable list of all user-defined scalars, from which you can select each one and specify its diffusion coefficient.

Coefficient   sets the diffusion coefficient for the selected user-defined scalar.
