what happened to this check on implicit_rotation_update ?

I think it is missing in fill_dt_omega_matrix

fill_dt_omega_matrix is only called within if (implicit_rotation_update == 1) I think.

in spherical coord, the position vector is just

Oh, this is because it is the position vector from the origin?

okay, everything looks good. can you also update the docs? |

PR summary
This addresses #2927 regarding the rotation bit.$\Omega \hat{z} = \Omega[\cos(\theta) \hat{r} - \sin(\theta) \hat{\theta})]$ .
I mainly separated
get_omega()to return magnitude of the angular frequency,then made
get_omega_vec()to depend on j, sinceTo deal with the problem of position vector, I just made sure
ris (r,0,0) before the cross_product call.I also made computing dt_omega_matrix into a separate function since omega vector now varies.
