Boundary Fitted Grid Module

The Boundary Fitted Grid Module is used for pre- and post- processing of 2D and 3D extracted boundary fitted grids. These grids consist of rows and columns of cells. Unlike Cartesian Grids, the cells in boundary fitted grids can have any quadrilateral shape and therefore are not necessarily aligned with the x/y cartesian directions. Because of this, the grid better fits the boundary of the model domain. In SMS, the Boundary Fitted Grid Module is used to create simulations for use with CH3D and ICM.

The CH3D coverage of the Map Module can be used to define the domain outline on a conceptual basis. After a grid has been set up, additional tools can be used to manipulate individual cells and to define boundary conditions. it is saved and the simulation analysis can be performed.

SMS currently supports only cell-centered grids. For these types of grids, solution data is reported as values at cell centers and fluxes across cell faces.
