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.

Dear Nektar++ users, I'm wondering if the current version Nektar++ incompressible flow solver can do simulation in cylindrical coordinates ? I found documents from the following website that shows it can, but didn't find the corresponding piece of code. https://prism.ac.uk/wp-content/uploads/2019/10/grocco_nektar.pdf Best regards Zhicheng Wang _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk<mailto:Nektar-users@imperial.ac.uk> https://mailman.ic.ac.uk/mailman/listinfo/nektar-users
