Re: [deal.II] Re: Finite Element Method for Two Phase Flow

Or, you could use as a stable pair of finite elements the FE_Q(k)-FE_DGP(k-1) pair: D. Boffi and L. Gastaldi. On the quadrilateral Q2-P1 element for the Stokes problem. Int. J. Numer. Meth. Fluids, 39 (2002), 1001-1011. This pair of finite elements is known to produce consistently better result

[deal.II] Re: Finite Element Method for Two Phase Flow

I would like to add an idea I intend to apply but right now am clueless of how to apply. In the earlier post I mentioned issue of 'spurious currents'. In the past researchers have tried quite a few approaches to handle this. One of them involves reconstruction of computed pressure field. In ess

Daniel, I had went through step-21 and it appears step-43 extends step-21 with the intentions of improving preconditioning et cetera. In essence both the tutorials solve the same set of equations, namely Darcy's Law, conservation of mass and saturation equation. But for this set of approximate
