3.5.1 Exporting 1D fields

1D Fields window allows exporting the 1D fields to the *.de3 file with button in Export tab and Export->Save as… command from main menu or context menu. The *.de3 file contains instantaneous field and lower and upper envelope data.

1D Fields window allows also exporting the time domain 1D fields to the *.tpd and consecutive *.tpd1, *.tpd2, *.tpd3,… files. Such files contain consecutive batches of N time probes of instantaneous field and were created according to Save time scale settings in Position & Parameters, Choose Source/Probe/Lumped, Choose NTFFA Postprocessing or Choose Source dialogues.

Example 1: format of *.de3 file with 1D field envelope for the wgtocx1m1 project

Envelope of Ez field along the x axis at y=16 and z=8 coordinates, built from iteration 10716 for 944 iterations, and a section of the saved wgtocx1m1.de3 file.

The *.de3 format includes a header with information about the project and envelope details. The numerical data organised in five columns:

1. cell number

2. cell position [mm]

3. instantaneous field value (middle thin line in Fields Display)

4. positive envelope value (upper thick line)

5. negative envelope value (lower thick line)

The field values are scaled as explained in Electromagnetic fields.

Example 2: format of *.de3 file with time-history of temperature for the heat_auto project

When thermal components (temperature or enthalpy) are saved in QW-BHM, header of the *de3 file is extended with additional BHM information. Time-history of temperature in heat_auto project, for x=20, y=23, z=6 coordinates, constructed from the beginning of the simulation until heating time of 80 sec.
