Galerkin Approximation for Finite Elements
so I've been trying my hand at this approximation but I can't quite seem to get a good answer. Would really appreciate if anyone can identify where I've gone wrong. Given a first order DE:
$$u''-\frac{6}{x^2}u+\frac{12}{x}=0,1

discontinuous galerkin method double-valued boundary values
when looking at a simple example for a DG-Method, lets make the domain go from 0 to 2, with one point in the middle:
\begin{align}
-u''=f
\end{align}
we would multiply with a smooth function and integrate by parts:
\begin{align}
\int_0^2…

About Finite Elements Method and stabilization using Upwind Scheme
I'm asking here cause I have a doubt about approximate solution of this problem:
\begin{equation}
\begin{cases}-\epsilon u''+bu'=0 \\ u(0) = 0, u(1)=1 \end{cases}
\end{equation}
which is a diffusion transport problem. I found the approximate…
