PFSS+GCS = $\theta_{BN}$ angle
Hello, I was wondering if the extrapolated magnetic field obtained from the PFSS model was merged with the GCS model here, Is it possible to estimate the "theta_BN" angle from the 3D mesh at a pre-defined number of points and show it on the 3D mesh?
NB. the theta_BN angle is the angle between the magnetic field line and the normal vector on the shock surface at that point.
That could be possible because the GCS is based on the assumption of a flux rope and its geometry shape. But I am just not sure about the precision or the accuracy of that calculation. And GCS is for eruption situation while PFSS is assuming a quiet sun. Unless you could have the change of magnetic field with time, which as I know typically from MHD simulation, otherwise, I can not combine them together.
