CIGRF.CalcVV Method

CIGRFCalcVV Method

Calculate IGRF data VV's for a given IGRF model.

Available since Oasis montaj version: 5.0
License: Available to anyone with an Oasis Montaj license.

Namespace: GeoEngine.Core.GXNetX
Assembly: geoengine.core.gxnetx (in geoengine.core.gxnetx.dll)

Notes

Calculate IGRF data (total field, inclination, and declination) for a given IGRF model. The model used will be the same as that obtained with Create_IGRF. All of the VV's should be the same length. The function will abort if they are not. No assumption is made on what data types are contained by any of the VV's. However, all total field, inclination, and declination values are internally calculated as real data. These values will be converted to the types contained in the output VV's.
