GridBoundaryFunc

Works with XSimBase license.

Block to define any shapes in the simulation.

GridBoundaryFunc Parameters

The GridBoundary block takes the following parameters:

kind (required string): Defines the type of grid boundary. Currently, the only option is kind = gridRgnBndryCrossDev.

dmFrac (optional float, default = 0.5): The fractional edge length below which the fraction will be rounded down to zero.

overlap (required int vector): The number of guard cells needed in the simulation

STFunc sub-block (required sub-block): A sub-block representing a function that defines the geometry. This can have its own kind, and the valid choices are expression and signedDistToSurfaces.
