I want to simulate particle motions in a annular-sector domain, and periodic boundary condition is needed to set in side boundaries. Is there method to set rotational periodic boundary condition?
The short answer is “no”. The more complex answer is - there is some code in MFiX for cylindrical coordinates, but it is unsupported, and the MFiX GUI will not allow you to create or open mfx files with coordinates=cylindrical. You can try to create a cylindrical coordinate case with a text editor, but you are on your own if you do this - cylindrical coordinates have been deprecated and we no longer support this option.
