gdsaddstencil – Script command – Ansys Optics

FDTD MODE

Adds one or more polygon elements to the current gds cell based on a slice formed by the intersection of a given z-plane and structures with a specific material and a partial name. Multiple polygons are created when there are more than 8190 vertices. You can only use this command if a gds cell has already been created, for example, using gdsbegincell.

If the material is “<Object defined dielectric>", the index value must be provided.

This command will always ignore disabled geometry.

Syntax	Description
gdsaddstencil(f, layer, {"material": mat_name, "partialname": partial_name, "z": z, "curve_chord_tol": tol, "dx": dx, "dy": dy });	Adds one or more polygon elements based on the intersection of a z-plane and structures. The parameters are explained below.

Parameter	Type	Description
f	string	A file handle that was previously opened with gdsopen.
layer	string or number	String: a string of the form "layer:datatype" (for example "6:2") can be used to define the layer number and datatype for this structure from the GDSII file to import. Layer and datatype are integers. Number: defines the layer number and sets the datatype to be zero.
mat_name	string	Material name for intersection. The command creates polygon(s) only for materials with this name.
partialname	string	Partial name of object for intersection. The command creates polygon(s) only for objects in the object tree that has this string as a part of its name.
z	number	The z-plane to create the intersection on. Only a scalar value is accepted.
curve_chord_tol	number	Optional with a default of 0. The maximum chordal distance between a facet edge and its original edge entity.
dx	number	Optional with a default of 0. Position within the slice to be used as the origin of the gds coordinates.
dy	number	Optional with a default of 0. Position within the slice to be used as the origin of the gds coordinates.
