class Backend_CUDA:

View In Hierarchy

Implements the Biot-Savart law for calculating the magnetic flux density (B-field) and vector potential (A-field). Backend: JIT + CUDA.
Static Method worker Applies the Biot-Savart law for calculating the magnetic flux density (B-field) or vector potential (A-field) for all sampling volume points.
Method __init__ Initializes the class attributes.
Method get_result Calculates the field at every point of the sampling volume.
