Faces of a cell

openfoam loop cell faces of a cell and get the corresponding cell face normal, noting that the normal vector direction points from low cell ID to the higher one

I decided to post my question inside this thread, as it is also somehow connected with looping over faces in a given cell. What I try to achieve is to get the face normal vector at every face in the cell, regardless it is a boundary cell or internal.
I produced the following code...:

My best guess is that the automatic memory handling in OpenFOAM, unintended is freeing the memory of the FORTRAN

Regarding your question, the following is my sample code:

Code:

scalar sumA = 0.0; //Sum of areas of all faces of a cell
const cell& cFaces = mesh.cells()[yourCellIndex];

forAll(cFaces, i)
{
    sumA += mag(mesh.Sf()[cFaces[i]]); //cFaces[i]: face label of a cell
}

scalar Length = mesh.V()[yourCellIndex]/sumA;

Step-by-step SU2 clean parallel Installation (Part 3/3)

Posted July 27, 2014 at 22:15 by pdp.aero
Updated October 4, 2015 at 13:28 by pdp.aero (Updating to recent version)

For the past

In this section, we are going to install the SU2 2.0.2, pretty old version comparing to current version 3.2.0, and then SU2 2.0.10, after we will finally install the SU2 3.0.0. Again, download the tar file, put the source in a right place, and unpack it. Before building these versions we will need the stands-alone metis.

Metis 4.0.3

Download the tar file from here, put it in your SU2 2.0.2 trunk, then unpack the tar file and direct there....
