Type: class │ Base(s): AbstractSubpixelAveragingMethod
Description
Section titled “Description”Apply a subpixel averaging method known as conformal mesh scheme to PEC boundaries.
The algorithm is based on:

Parameters
Section titled “Parameters”timestep_reduction [float] = DEFAULT_COURANT_REDUCTION_PEC_CONFORMAL |
|
Reduction factor between 0 and 1 such that the simulation’s time step size is |
edge_singularity_correction [bool] = True |
|
Apply field correction model at metallic edges where field singularity occurs. The edges should be straight, and aligned with the primal grids; and the wedge angle is either 0 or 90 degree. |
Methods
Section titled “Methods”courant_ratio() |
|
The scaling ratio applied to Courant number so that the courant number in the simulation is |
