GridBoundaryCondition.Fill Method

public static GridBoundaryCondition Fill(
	double value
)

Public Shared Function Fill ( 
	value As Double
) As GridBoundaryCondition

public:
static GridBoundaryCondition Fill(
	double value
)

static member Fill : 
        value : float -> GridBoundaryCondition 

Parameters

value  Double

The constant value to use when the stencil requires samples outside [0, N-1].

Return Value

When an interpolation stencil requires a value at index i < 0 or i ≥ N, the specified constant value is returned instead of a grid value.

Effect: Out-of-range samples in the stencil are replaced with the constant value. This can create discontinuities or artifacts at grid edges, depending on the fill value.

Use cases:

• Padding data with zeros or a known background value.
• Isolating the grid interior from edge effects.
• Simulating data embedded in a constant field.

Common values: 0.0 (zero padding), double.NaN (mark invalid regions), or a domain-specific background value.
