assign_matrix#

Maxwell3d.assign_matrix(assignment, matrix_name=None, turns=None, return_path=None, group_sources=None, branches=None)[source]#

Assign a matrix to the selection.

Matrix assignment can be calculated based upon the solver type. For 2D/3D solvers the available solution types are: Magnetostatic, Electrostatic, Eddy Current, DC Conduction and AC Conduction.

Parameters:

assignmentlist, str: List of sources to assign a matrix to.
matrix_namestr, optional: Name of the matrix. The default is None.
turnslist, int, optional: Number of turns. The default is 1.
return_pathlist, str, optional: Return path. The default is infinite
group_sourcesdict, list optional: Dictionary consisting of {Group Name: list of source names} to add multiple groups. You can also define a list of strings. The default is None.
branches: list, int, optional: Number of branches. The default is None, which indicates that only one branch exists.

Returns:

pyaedt.modules.Boundary.BoundaryObject: Boundary object.
