Simulation3DDifferential.projectFields(u)[source]#

This function projects the fields onto the data space. Especially, here for we use total magnetic intensity (TMI) data, which is common in practice. First we project our B on to data location

$${\mathbf{B}}_{rec}=\mathbf{P}\mathbf{B}$$

then we take the dot product between B and b_0

$$\text{TMI}={\overrightarrow{B}}_s\cdot {\hat{B}}_0$$
