export_matrix

Maxwell2d.export_matrix(matrix_name: str, output_file: str | Path, setup: str | None = None, is_post_processed: bool | None = False, default_adaptive: str | None = 'LastAdaptive', is_format_default: bool | None = True, width: int | None = 12, precision: int | None = 6, is_exponential: bool | None = False, use_independent_nominal_values: bool | None = True) → bool

Export matrix after solving.

This method exports matrix data from the Matrix tab in the Solutions window to a .txt file.

Parameters:

matrix_namestr

Matrix name to be exported.

output_fileor pathlib.Path

Output file path to export matrix file to. Extension must be .txt.

is_format_defaultbool, optional

Whether the exported format is default or not. If False the custom format is set (no exponential).

widthint, optional

Column width.

precisionint, optional

Decimal precision number.

is_exponentialbool, optional

Whether the format number is exponential or not.

setupstr, optional

Name of the setup. If not provided, the active setup is used.

default_adaptivestr, optional

Adaptive setup name. The default is "LastAdaptive".

is_post_processedbool, optional

Boolean to check if it is post processed. The default value is False.

use_independent_nominal_valuesbool, optional

Whether to use independent nominal values when retrieving variations. The default value is True.

Returns:

bool

True when successful, False when failed.

Examples

The following example shows how to export capacitance matrix from an Electrostatic solution.

>>> from ansys.aedt.core import Maxwell3d
>>> m3d = Maxwell3d(version="2025.2", solution_type="Electrostatic", new_desktop=False)
>>> up_plate = m3d.modeler.create_box(origin=[0, 0, 3], sizes=[25, 25, 2], material="pec")
>>> gap = m3d.modeler.create_box(origin=[0, 0, 2], sizes=[25, 25, 1], material="vacuum")
>>> down_plate = m3d.modeler.create_box(origin=[0, 0, 0], sizes=[25, 25, 2], material="pec")
>>> voltage1 = m3d.assign_voltage(assignment=down_plate.name, amplitude="0V", name="voltage1")
>>> voltage2 = m3d.assign_voltage(assignment=up_plate.name, amplitude="1V", name="voltage2")
>>> # set matrix and analyze
>>> matrix = m3d.assign_matrix(assignment=[voltage1.name, voltage2.name], matrix_name="Matrix")
>>> setup = m3d.create_setup()
>>> setup.analyze()
>>> # Export C Matrix after solving
>>> m3d.export_matrix(matrix_name=matrix.name, output_file=Path(m3d.working_directory) / "C_matrix.txt")
>>> m3d.desktop_class.close_desktop()
