Member Data Documentation

◆ accumulate

bool SimLaplacianOperatorConfig::accumulate

Add into the output when true.

◆ axis_x

size_t SimLaplacianOperatorConfig::axis_x

First derivative axis, or SIM_LAPLACIAN_AXIS_AUTO.

◆ axis_y

size_t SimLaplacianOperatorConfig::axis_y

Second derivative axis, or SIM_LAPLACIAN_AXIS_AUTO.

◆ boundary

SimIRBoundaryPolicy SimLaplacianOperatorConfig::boundary

Boundary policy for out-of-range neighbors.

◆ input_field

size_t SimLaplacianOperatorConfig::input_field

Source field index.

◆ output_field

size_t SimLaplacianOperatorConfig::output_field

Field receiving the Laplacian.

◆ scale_by_dt

bool SimLaplacianOperatorConfig::scale_by_dt

Scale writes by substep dt when true.

◆ spacing_x

double SimLaplacianOperatorConfig::spacing_x

Grid spacing along axis_x; non-positive values normalize.

◆ spacing_y

double SimLaplacianOperatorConfig::spacing_y

Grid spacing along axis_y; non-positive values normalize.

◆ stencil

SimLaplacianStencil SimLaplacianOperatorConfig::stencil

Finite-difference stencil family.
