[FLASH-USERS] 2.5D split hydro & centrifugal force

    Hi all,

Does FLASH support 2.5D split hydro including a centrifugal force term? 
The users' manual clearly explains that 2D cylindrical support is 
available, and that the missing phi-coordinate implies that the solution 
is integrated around the symmetry axis (z-axis; all variables are 
independent of the phi-coordinate). But can one compute the velocity in 
the phi-direction v_phi, in addition to v_r and v_z, to account for the 
centrifugal forces in a system rotating around the z-axis? (obviously, 
such-defined v_phi would be independent of phi as the system is 
two-dimensional). Or is this something that still needs to be implemented?

    Thanks,
      Mateusz
