Posted October 30, 2016 at 18:50 by albertsk
Updated November 6, 2016 at 17:12 by albertsk

This blog is to show how to install OpenFOAM-v3.0+ on Ubuntu 16.04 LTS. There are some issues that should be resolved before the installation. So far, default compilers installed in Ubuntu, gcc and openmpi, are used. Compilation of OpenFOAM-v3.0+ using Intel compilers is on-going.

After you unzip the package OpenFOAM-v3.0+.tgz under ~/OpenFOAM, go to the directory
Code:
cd OpenFOAM-v3.0+
open the following file
Code:
emacs src/postProcessing/functionObjects/Allwmake

  1. Apply the "Slice" filter, along the direction of your original line.
  2. Apply a second "Slice" filter, applied to the first one, along the location of the intended line.
  3. You should now have the same line you originally intended, but with some extra information that the "Plot over

Detached-Eddy Simulation (DES) models in OpenFOAM

Posted October 23, 2016 at 10:03 by fumiya

Detached-Eddy Simulation (DES) is a hybrid Reynolds Averaged Navier-Stokes (RANS)/Large-Eddy Simulation (LES) model.
The DES model was first proposed in 1997 by Spalart et al. [1] based on the Spalart-Allmaras RANS model and
it is commonly referred to as DES97.

I've summarized DES models available in OpenFOAM in the following post:

A generalized thermal/dynamic wall function: Part 3

Posted October 17, 2016 at 11:25 by sbaffini (NuTBox)
Updated December 21, 2016 at 10:06 by sbaffini

In this post i summarize the initial problem and the procedure to determine the wall function value (i.e., the solution) for given y^+,F_T^+,Pr and Pr_t.

We looked for a solution T^+\left(y^+,F_T^+,Pr,Pr_t\right) to the problem:

\frac{dT^+}{dy^+}=\frac{Pr\left(1+F_T^+y^+\right)}{\left[1+\left(\frac{Pr}{Pr_t}\right)\left(\frac{\mu_t}{\mu}\right)\right]}

with:

\frac{\mu_t}{\mu}=\frac{\left(ky^+\right)^3}{\left(ky^+\right)^2+\left(ka_0\right)^3-\left(ka_0\right)^2}...
