editThis article has unfortunately enough been written solely from memory. I searched for good sources, but could not find any. It would be great if someone could provide a good source. Bfg 13:29, 16 November 2006 (UTC)
This really does not make sense -- D Laplace Psi is a scalar, |u|=1 => u ( u * D Laplace Psi ) = D Laplace Psi —Preceding unsigned comment added by 129.13.156.50 (talk) 14:34, 25 March 2010 (UTC)
The streamline diffusion is Divergence (u D u . Gradient Psi) but it is not the only mistake in the equation. The sign of the diffusive term is wrong as well. For a reference, it could be interesting to show that the weak form obtained after integration by part correspond to what is in Elman, Silvester, Wathen 2005, Oxford University ("Finite Elements for incompressible flows or something like this") —Preceding unsigned comment added by 91.178.186.13 (talk) 19:17, 14 March 2011 (UTC)
Context
editCould someone please explain what we're talking about here? Is this fluid dynamics? No fair typing random equations out of the book and pretending they are articles. --Wtshymanski (talk) 13:38, 14 June 2011 (UTC)
