Public Functions Documentation

function CalcInitnblk

Calculates the initial number of blocks for the mesh.

int CalcInitnblk (
    Param XParam,
    Forcing < float > XForcing
)

Parameters:

XParam Model parameters (resolution, block size, etc.)
XForcing Forcing data (bathymetry, AOI polygon, etc.)

Returns:

Number of blocks to allocate for the mesh.

This function divides the domain into uniform blocks, checks masking and AOI, and counts blocks that are active for computation.

Parameters:

XParam Model parameters
XBlock Block data structure

Returns:

Number of blocks with masked neighbors.
