<div dir="auto">Correct me if I’m wrong but I’m not sure that’s 100% correct, Klaus. Even without b-field variables (i.e., pure Hydro) AXISYMMETRIC boundary conditions will flip the sign of VELZ, treating as though it is the rotational velocity for a “2.5D”
simulation.

I did not follow the details of the previous exchange, but want to confirm<br>
that you are correct on this point: In the absense of magnetic field<br>
variables, 'axisymmetic' and 'reflect(ing)' boundary conditions are meant<br>
to be completely equivalent.<br>
