Rsoft Cad Manual [extra Quality] Guide

You must define how light enters your structure via the window:

It is crucial to understand the coordinate systems used (e.g., x, y, z for 3D or x, z for 2D). RSoft strictly adheres to standard optical conventions, where the direction of propagation is often chosen as the z-axis.

The manual and technical articles on RSoft provide a powerful workflow for designing components like the diffraction gratings used in Augmented Reality (AR) glasses, often combining multiple simulation engines: rsoft cad manual

Grid size is too large or time-step violates the Courant stability criterion. Reduce spatial grid size ( Δcap delta

The manual is designed to guide users through the intricate process of defining optical structures. Unlike standard mechanical CAD tools, RSoft is built specifically for photonics; therefore, the manual focuses heavily on how geometric definitions translate into electromagnetic boundary conditions. It covers the complete workflow: defining material properties, drawing 3D structures, setting simulation parameters, and running computational engines like BeamPROP, FullWAVE, and ModePROP.
