&CELL: FIELD-MAP: FILES


contents

One may specify the contents of the file before the name. This is mandatory in the following cases:

In case Maxwell Field Simulator has been used to generate the maps, identifying the mesh directory is recommended. The contents is optional for all other types of data written by Maxwell programs.

A warning is issued if the file contains other data than the declared contents.

Currently, the following contents types are recognised:

Name Used to compute
B-FIELD (=MAGNETIC-FIELD) Drift lines
ELECTRIC-FIELD Drift lines, various other plots
D-FIELD Epsilon by comparing E and D
MATERIAL (=D-FIELD) Drift line termination
MESH Always needed with Maxwell Field Simulator
POTENTIAL (=VOLTAGE) Contour maps
WEIGHTING-FIELD Induced signals


file

The name of the dataset that contains the field map or the mesh.

These files are usually written by other programs than Garfield, and they therefore do not follow internally the Garfield format conventions. For notes on the way dataset names should be supplied to Garfield, see the guidelines for Garfield files.

For recipes for making these files, refer to the file format descriptions.


label

The label is a single upper case alphabetic character which serves two purposes:
  1. The label links a weighting field with solids. For this association, the weighting field label should match one or more labels used in the SOLIDS listing. A solid label should not match more than one weighting field label, unless the signals for these weighting fields are summed.

    In the absence of a match, e.g. because no solids have been entered, all signals on the weighting field map are classified as cross induced. Such signals are only computed if the CROSS-INDUCED option is active.

  2. The label identifies the weighting field to the SELECT statement, a prerequisite for the computation of signals in the electrodes for which the weighting field has been computed.

No label should be assigned to other fields than the weighting fields.

[By default, the label "S" is assigned to weighting field maps, which makes these maps are part of the initial, default, selection.]


format

Specifies the program that has been used to generate the field maps. Currently, the following formats are accepted:

With the exception of Tosca, all formats are automatically recognised, and a format doesn't have to be specified therefore.

Recipes for creating field maps with these programs are given in the sub-topics.
