Hi!
I am in need of a new type of basis function for testing purposes. It is much similar to the basis functions of the Taylor-Hood P1 element, the difference is that the functions are piecewise constant equal to 1 in this "local domain" (similar for 1D and 3D): [http://www.fsz.bme.hu/~szirmay/radiosit/rad10.gif] and zero in the rest of the domain. In general, phi_i = 1 for "local domain of dof i", 0 else. Would it be possible to implement this without too much work? Or would it require a lot of effort? Thanks!
