Installation of OpenFOAM 2.3.0 / 2.3.x on RHEL 5.8 without root permissions

Posted July 7, 2017 at 03:08 by kindle
Updated July 10, 2017 at 03:55 by kindle (add the right way to check the interior mesh)

Take a look at the paraview setting.

Here is a page saying that to check the mesh inside a geometry (https://openfoamwiki.net/index.php/FAQ/Postprocessing). The right thing to do is not the clip nor the slice. But
1. load the case unchecking polyhedral decomposition
2. filter : Extract Cells by Region

On the explaination of laplacianFoam
This is extracted from the blog dyfluid.com.

Code:

volVectorField gradT(fvc::grad(T));//创建gradT场，其值为fvc::grad(T)，即为∇T显性离散的值          
volScalarField gradTx

Reology with Fortran program available

Posted June 7, 2017 at 12:11 by kindle

This phd on Reology may be interesting.
Code : http://www.vvpf.net/download.html

Here he talked about memory function and a big memory footprint which will need special treatment in programming.

I just send you the paper you asked, and it might be a use after all, for your problem.
If you look at Eq. (8) in the paper (see also eq

scotch may not be built by icc.

SAS – cutting on your computational budget in an unsteady*manner

Posted May 18, 2017 at 16:47 by Avr.Tomer

The following is taken from*CFD ISRAEL*blog (thoughts of a CFD blogger), addressing a branch of Scale Resolving Simulation known as 2nd generation URANS.
The specific SAS model is a*2-equation*unsteady RANS model, able to get very good quantitative results for many unsteady flows even on a relatively coarse mesh.
