Building OpenFOAM1.7.0 from source

Posted August 25, 2010 at 18:08 by maysmech

Needful installation to ./Allwmake in in the folder $WM_PROJECT_DIR/OpenFOAM-1.7.0:installation several packages, and the one in particular that you are missing is build-essential.
This is a command line that will install most of the necessary (and some possibly unnecessary) packages for building OpenFOAM and ParaView:

Code:

sudo apt-get install binutils-dev flex bison git-core build-essential python-dev libreadline5-dev wget zlib1g-dev cmake libpng12-dev libxt-dev libxi-dev libxrender-dev

Flux computation in unstructured grids

Consider finite volume scheme on unstructured grids for the Euler equations.

Let

be normal to a cell face and whose magnitude is equal to face area. Let

be the conserved vector. The finite volume update equation using forward Euler time discretization is

$Q^{n+1}_j = Q^n_j - \Delta t \sum_{k \in N(j)} F(Q_j^n, Q_k^n, n_{jk})$

Here $n_{jk}$ is a normal vector pointing from current cell "j" into the neighbouring cell...

Elmer and deal.ii

Posted July 9, 2010 at 10:48 by praveen (CFD, Numerical Analysis, Scientific Computing)

There are two PDE solvers that I came across recently which look good. Both are FEM based.

Elmer has a good gui and has many physical models already available. There is a good amount of manuals and tutorials available. To get all of them, check out the code from svn. It also has some ability to program your own solvers but this is not well documented. It is a good aid for teaching numerical methods. Windows executable can be downloaded from their website. There is also a Mac binary...

Adjoint consistency of DG method

Adjoint Consistency Analysis of Discontinuous Galerkin Discretizations
SIAM J. Numer. Anal. Volume 45, Issue 6, pp. 2671-2696 (2007)
http://dx.doi.org/10.1137/060665117

This paper gives a notion of consistent adjoint discretizations for DG methods. However the definition seems to be restricted to smooth solutions only. For the case of a conservation law, they show that boundary conditions of the primal problem must be appropriate for the corresponding adjoint discretization...
