3D File Format for GMD/HEMP Event Inputs

The B3D binary file format uses little-endian order and holds two-dimensional, time-varying data such as electric fields on the surface of the earth. Because the magnitude and direction can be non-uniform in time and space, it can be used where a 3D earth resistivity model is assumed. Applications in PowerWorld Simulator include geomagnetic disturbance (GMD) […]
