Function Documentation

function [ flux , lambda ] = conv_flux_burgers	(	glob,
		U,
		params
	)

function computing the convective flux of a Burgers problem.

flux is a 2xnpoints matrix, representing the x/y-coordinates of the velocity in the edge midpoints.

Parameters:

glob	a matrix of row vectors for each coordinate dimension of the grid defining the coordinates where the flux function is evaluated, in case it is space dependent, i.e. we have something like .
U	a vector with evaluations of a solution which are passed as an argument to the flux function
params	a structure with model parameters

Return values:

flux	a matrix which entries $F_{ji}$ represent the -th component of the flux vector $f(u(x_{j}))$ in the edge midpoint $x_{j}$ given by the `glob` argument.
lambda	a bound such that $\lambda \cdot \sup_u n_{jl} \cdot f'(u) \leq 1$ e.g. $\lambda := \frac{1}{\sup\|v(x,y)\|}$ for $f(u) = v \cdot u$ . This is value only reasonable in `decomp_mode==0`, otherwise an empty variable is returned.

Required fields of params:
