Hmm perhaps they just mean 2 components, funny they stress 2 function for P4 but not for P3. What do you mean by local dimension 3? Do you mean the spatial dimension or 3 basis functions? > > Are you sure that you have the latest ffc? Yeah. But I can put anything 3 and above as the order and it looks to work. I just want to make sure I have some vague notion of what I am doing. > > -- > 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
