I am working to impletement the FM torus for generalized metric. I have derived the generalized calculation for the torus setup using BL coordinates. But when I need to convert BL to KS, there is in the kerr_schild.cpp I am getting a bit confused with the following portions:
Calculate intermediate geometric quantities: r, \theta and \phi direction
EdgeXLength functions, FaceXArea functions and Cell Volume function
Could you please let me know how to proceed with it for any stationary axisymmetric metric other than Kerr?
