CSV to B3D V4 converter written in Go. B3D is a binary format for Powerworld (TM) Simulator used to store time- and spatially-varying geoelectric field data.
For more information on the B3D file format, refer to the PowerWorld (TM) documentation:
https://www.powerworld.com/knowledge-base/b3d-file-format
To Build: go build csv2b3d.go
To Run: csv2b3d <csvdir> <b3dfile>
To set a message in the header: csv2b3d -message "<message>" <csvdir> <b3dfile>
To set an optional time step in seconds: csv2b3d -step <time_step> <csvdir> <b3dfile>. Note that the default time step is 60 s.
To only run on the first n files: csv2b3d -times <count> <csvdir> <b3dfile>
For help: csv2b3d -help
Batch Conversion: For an example of a PowerShell 7.x script to process a folder
of folders of input CSV files in parallel, see Csv2B3d.ps1
The input CSV files are expected to have a header line and data lines in the following order:
- Latitude (-180 to +180 degrees)
- Longitude (-180 to +180 degrees)
- West-East component of electric field
- South-North component of electric field
Additonally, the CSV files should be named with leading zeros such that a string sort will return the correct order, e.g.
input01.csv
input02.csv
input03.csv
input04.csv
input05.csv
input06.csv
input07.csv
input08.csv
input09.csv
input10.csv
