@je-cook I think this papercut issue is somehow related to a bigger discussion: https://github.com/ukaea/PROCESS/issues/3119#issuecomment-2124696458

Also found similar discontinuities in other reactor examples, e.g. STs. If @CoronelBuendia or @DarioV86 have any suggestions that would be extremely helpful. My idea is that it goes as back...

Not only for sol_rad, happening for cor_rad too. If you run self.plot_radiation_distribution() after calculating core distribution (L506, bluemira.radiation_transport.radiation_profile): 

I came to believe that, The grid-like behaviour is not coming from the interpolation, but actually originated from the flux tubes in source itself. It is only getting pronounced in...

Had a discussion with @DarioV86 Some points: EUDEMO: (less points, grid: 65 x65) 

For Discussion in Monday's Meeting: Me and @DarioV86 chatted last Monday, and added an optional argument to add interpolated points when flux surfaces are made. The associated branch is `anilima/papercut_#3944`...

Just noting down my thoughts below for reference: 1. Currently, `_check_discretisation()` only compares the maximum edge length with the total length, which for a circular curve roughly corresponds to comparing...
