Compile the solver laplacianFoam

Posted August 17, 2016 at 10:22 by kindle
Updated February 23, 2017 at 04:13 by kindle
laplcacianFoam is an implemented solver in OpenFOAM, which can be found in WM_PROJECT_DIR/platforms/.../bin (executable), .../application/solver/basic (dep) and WM_PROJECT_DIR/application/solver/basic (src).

Tried to compile from $FOAM_RUN, using laplacianFoam1. After comparing with authentic one, success.

Writing the last iteration for steady state simulations

Posted August 17, 2016 at 05:09 by Ramwi
Ok, I have a very bad memory and furthermore, I did not find the solution to the bellow described problem right away. So, I will use this place to store the solution for future use.

Note: The proposed approach might be overcomplicated. If it is so, please let me know what is the "proper way".

Problem description: You run a steady state simulation (e.g. simpleFOAM) and you control the endTime (number of iterations) via the residualControl. Thus, the number of iterations...

I was able to implement my boundary condition as well. I used the following code to access the internal velocity field and the mesh two layers of cells inward from the boundary:

Code:

    const volVectorField& U =
        db().objectRegistry::lookupObject<volVectorField>(UName_);
    const fvMesh& mesh = patch().boundaryMesh().mesh();

How to calculate the polynomial coefficients of any arbitrary polynomial to fit data

Posted August 1, 2016 at 08:06 by Tobi
Dear all,

if you are interested in the calculation of polynomial coefficients to fit some data, you can check the method of least squares on my homepage. Here I explained everything in detail and also gave an example how to build the matrix A and the solution vector b for the problem we are discussing there. The polynomial that I am using in the example is:

\ln(\mu) = A + B \ln(T) + C\ln(T)^2 + D \ln(T)^3

How to build the matrix A and the solution vector...

Parallel installation incorrectly compiled

Posted July 23, 2016 at 11:35 by ACGray
Problem solved, turns out I had both OpenMPI and MPICH installed which I think was throwing off the mpirun command, uninstalled both, reinstalled MPICH 3.2 and then SU2 and everything now seems to be working fine!
