stepimport - Script command – Ansys Optics

FDTD MODE DGTD CHARGE HEAT FEEM

Adds a structure to the simulation environment with structure geometry loaded from specified STEP file.

Syntax

Description

stepimport("filename",scale_factor);

Add new structures from specified STEP (AP203/214) type CAD file. Supports multi-body parts. Only manifold solid bodies are imported - wires, surfaces, and faceted solids will not be imported.

SCALE_FACTOR (optional):

Allowed values are 3, 0, -3, -6, -9, corresponding to the options of the STEP import dialog. For example, the value -9 means that a STEP 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 the finite-element IDE 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 can be used to create a 3D geometry based on the file provided in this KB page: Import - STEP .

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