Abstract
The application describes various techniques for improving the accuracy and numerical stability of computer-implemented simulations which employ subgridding techniques. In particular, techniques are described in which information is transferred across a common interface between two neighboring fine-grids. Furthermore, techniques are also described in which, during the update of a grid in regions where there exists an embedded fine-grid, the field values at co-located edges at which fine-grid solution points exist on the grid, are summed and used in an approximation of the gradient term required for the FD-TD updating stencils to perform an electromagnetic simulation.
