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!

Dear All
I am an experimental person, learning FEM and its software on my own. I wish to develop a program in Java for solidification analysis of castings. This is the purpose of joining this forum. Hope your support will be extended.
Thanks

11th community OpenFOAM Workshop: finally managed to attend one of these! Part 3

Posted July 3, 2016 at 12:43 by wyldckat
This is the third part of a long blog post, see the first part here and the second here.

On the 30th:
  • I arrived at around 08h10, had to meet+talk with Miguel Nóbrega to see how the clinics sessions were going to be organized.
  • The first (and only) lecture was given by Fred Mendonça, with the title "Custodians of OpenFOAM®".
    • He told us about his career experience. In a nutshell: a lot of experience, both CFD and business/management!
    • Told us and showed us a map
