The data structure for the .ol files are described to understand and correctly post-process these files externally.
The following fields are available in the header block:
Key | Required | Description |
---|---|---|
File Type | Yes | Describes the type of the file. For surface charge density, the value must be Charges. |
File Format | Yes | Denotes the file syntax version (such as “4”). If not present it defaults to version 1 (files pre-dating Feko 6.1). |
Source | Optional | Denotes the base filename of the source where this data comes from. |
Date | Optional | Date and time of data export in format “YYYY-MM-DD hh:mm:ss” (that is 24-hour format). |
The following fields are available in the solution block header:
Key | Required | Description |
---|---|---|
Configuration Name | Optional | The configuration name, if present. |
Request Name | Optional | The explicit name given to that solution request (as denoted in the .pre file). If none is specified, POSTFEKO will use a default name of “request_N” (where “_N” is replaced with a number for each unnamed request) during import. |
Frequency | Yes | Frequency in Hz for which the following data was measured/computed. |
No. of [$$$] Samples | Yes | The number of samples in each axis direction. The “[$$$]” term is replaced

Yes | For header lines, the following format should be
used:
|
Num X Y Z Re(Q) Im(Q) [optional] Surface Area
Num X Y Z Re(Q) Im(Q) [optional] Length
