Neilen Marais posted a new comment: Hi Luis, I don't actually know much about fluid dynamics, (I'm an electromagnetics guy) but if by conservative you mean lossless (i.e. energy is conserved) in the case of lossless materials, then I think it is down to using the correct time integration scheme. For many problems you need to use a symplectic integrator: http://en.wikipedia.org/wiki/Symplectic_integrator, or depending of the FEM forumlation you start with, something like the Newmark-Beta method http://en.wikipedia.org/wiki/Newmark-beta_method. As for FEM/FVM equivalencies, again, I am not an expert in the particular field, but in general there are many methods that can be shown to be equivalen to the FEM given the correct test, trial and matrix integration schemes. In my field, it is quite easy to show equivalence between time-domain FEM methods and the finite difference time domain (FDTD) method. -- You received this question notification because you are a member of DOLFIN Team, which is an answer contact for DOLFIN. _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : dolfin@lists.launchpad.net Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
