Okay so Brezzi Fortin have just a bubble function with one node. Perhaps they meant P3 but their notation is ambiguous. ArnoldBrezziFortin1984 does call for the P3 in the original paper but then they mention using 2 P4 bubble functions for the next velocity order. If I do enrich with 2 P4 bubbles with ffc will the bubble functions be any different. It just seems like it will give exactly the same evaluation points as enriching with 1 bubble function.
I'm not quite sure what you mean by enriching with 2 P4 bubble functions. Do you mean 2 as in 2 components? Note that the bubble space of degree 4 has local dimension 3.
Are you sure that you have the latest ffc? -- Marie _______________________________________________ Mailing list: https://launchpad.net/~ffc Post to : ffc@lists.launchpad.net Unsubscribe : https://launchpad.net/~ffc More help : https://help.launchpad.net/ListHelp
