Hi,
I am new to CFD, and was going over one article,
it is about stokes equation using Finite element method.
It is formulated using Lagrange multipliers method. Where can I find out the basic stuff of about Lagrange multipliers method for weak formulation.
I saw Girault and Raviart's book 1979, but it is not there
thanks

I don't exactly know where it is,
but for me, the Bibble in Finite Element Methods is Zienckiewicz's book,
in particular, you can find the weak formulation in his CFD book os in some chapters of his old edition.
Hope it helps
