HI Zhicheng, We certainly started setting up a cylindrical coordinate formulation but have not touched in in quite a while. There might be an old branch with this capability. However we never got to setting up the Fourier extension of the formulation which would be required for a 3D (rather than just 2D) simulations. If you need 3D then I am afraid there is not much hope at the moment. If you only required 2D cylindrical we might be able to see where this branch might be. Cheers, Spencer.

Hi Prof. Spencer Sherwin, Thank you for the information. Actually I'm working on the old version Nektar, trying to add cylindrical coordinates capability, following the 2004 JCP paper by you and Prof. Blackburn, but failed to make it work. I know this email list isn't the right platform to ask you questions about old Nektar, but if you have any suggestions would be very appreciated.

Hi Zhicheng, The challenge we had in Nektar++ getting this to work is that difference Fourier harmonics require different types of boundary conditions. We have not had a chance to fix this yet. I do not recall if this is also an issue in the older version of Nektar++. Cheers, Spencer.
