cadimport - Script command – Ansys Optics

FDTD MODE DGTD CHARGE HEAT FEEM

Adds a structure to the simulation environment with structure geometry loaded from specified STEP or CAD file. This command is identical to stepimport.

Syntax

Description

stepimport("filename",scale_factor);

Add new structures from a specified CAD file. The list of supported file formats can be found in the Knowledge Base article on CAD import.

SCALE_FACTOR (optional):

Allowed values are 3, 0, -3, -6, -9, corresponding to the options of the STEP import dialog in Ansys Lumerical Multiphysics™. For example, the value -9 means that a file saved in meters will be read as if in nanometers. Structures will be imported as \(10^{-9}\) times the actual size.

When 'scale_factor' is omitted, 'no scaling' is applied

This function does not return any data.

Note: How to handle the "Model size exceeds valid box" error

The geometry in Multiphysics cannot exceed a maximum size, a fixed number of length units. This error can be avoided by changing the solver to use a larger length unit, or by supplying a smaller 'scale_factor' argument.

Example

The following script commands is used to create a 3D geometry based on the STEP file provided in the Knowledge Base article on CAD import.

filename = "stepimport.step";
cadimport(filename);

The following script commands is used to create a 3D geometry based on the SolidWork file provided in the Knowledge Base article on CAD import, using a scaling factor of \(10^{-6}\).

filename = "Caliper.SLDPRT";
cadimport(filename, -6);
