export

FieldsCalculator.export(quantity, solution=None, variations=None, output_file=None, intrinsics=None, phase=None, sample_points=None, export_with_sample_points=True, reference_coordinate_system='Global', export_in_si_system=True, export_field_in_reference=True, grid_type=None, grid_center=None, grid_start=None, grid_stop=None, grid_step=None, is_vector=False, assignment='AllObjects', objects_type='Vol')

Export the field quantity at the top of the register to a file, mapping it to a grid of points.

Two options are available for defining the grid points on which to export: - Input grid points from file : Maps the field quantity to a customized grid of points.

Before using this command, you must create a file containing the points and units.

• Calculate grid pointsMaps the field quantity to a three-dimensional Cartesian grid.

  You specify the dimensions and spacing of the grid in the x, y, and z directions, with units. The initial units are taken from the model. Other grid options are: Cylindrical, in which case rho, phi and z directions must be specified, or Spherical, in which case r, theta and phi directions must be specified.

If you want to adopt the first option you must provide either the file containing the grid of points or a list of sample points in sample_points. In the latter case, a new file is created in the working directory called “temp_points.pts” that will be automatically written with the data points provided and consequently imported. If you want to adopt the second option you must provide the grid type (Cartesian, Cylindrical or Spherical). If grid_center, grid_start or grid_stop are not provided the default values are used.

Parameters:

quantitystr

Name of the quantity to export.

solutionstr, optional

Name of the solution in the format "solution : sweep". The default is None.

variationsdict, optional

Dictionary of all variation variables with their values. The default is None.

output_filestr, optional

Full path and name to save the file to. The default is None, in which case the file is exported to the working directory.

assignmentstr, optional

List of objects to export. The default is "AllObjects".

objects_typestr, optional

Type of objects to export. The default is "Vol". Options are "Surf" for surface and "Vol" for volume.

intrinsicsdict, str, optional

Intrinsic variables required to compute the field before the export. These are typically: frequency, time and phase. It can be provided either as a dictionary or as a string. If it is a dictionary, keys depend on the solution type and can be expressed in lower or camel case as: - "Freq" or "Frequency" - "Time" - "Phase" If it is a string, it can either be "Freq" or "Time" depending on the solution type. The default is None in which case the intrinsics value is automatically computed based on the setup.

phasestr, optional

Field phase. The default is None. This argument is deprecated. Please use intrinsics and provide the phase as a dictionary key instead.

sample_pointsstr, list

Name of the file with sample points or list of the sample points.

export_with_sample_pointsbool, optional

Whether to include the sample points in the file to export. The default is True.

reference_coordinate_systemstr, optional

Reference coordinate system in the file to export. The default is "Global".

export_in_si_systembool, optional

Whether the provided sample points are defined in the SI system or model units. The default is True.

export_field_in_referencebool, optional

Whether to export the field in reference coordinate system. The default is True.

grid_typestr

Type of the grid to export. The options are: - Cartesian - Cylindrical - Spherical

grid_centerlist, optional

The [x, y, z] coordinates for the center of the grid. The default is [0, 0, 0]. This parameter is disabled if gridtype= "Cartesian".

grid_startlist, optional

The [x, y, z] coordinates for the starting point of the grid. The default is [0, 0, 0].

grid_stoplist, optional

The [x, y, z] coordinates for the stopping point of the grid. The default is [0, 0, 0].

grid_steplist, optional

The [x, y, z] coordinates for the step size of the grid. The default is [0, 0, 0].

is_vectorbool, optional

Whether the quantity is a vector. The default is False.

Returns

——-

bool or str

The path to the exported field file when successful, False when failed.
