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

Posted July 27, 2014 at 21:15 by pdp.aero
Updated October 4, 2015 at 12:28 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....

Dear Community,

I am happy and glad to tell you that I finished to analyze all my cases in the investigation of the "Influence of mesh size, orientation and type on numerical schemes in a convective flow field".

Information

  • Investigate into numerical schemes to convective flow field
  • Influence of schemes on mesh size
  • Influence of schemes on mesh type (structured / unstructured)
  • Influence of schemes on mesh/flow orientation (45degree / 0 degree)

Flamelet Model For OpenFOAM

Posted July 15, 2014 at 09:38 by Tobi

Dear all,

I am working in the topic of the steady state laminar flamelet model since 2012 and used this model in my master thesis for biomass combustion chambers. Therefor I used the built version from Alberto Cuoci et. al. which was generated for OpenFOAM-1.7.x. For my research I used a newer version of OpenFOAM due to the fact of released snappyHexMesh version. Bruno Santos rebuilt the flamelet model for OpenFOAM-1.7.x, 2.0.x, 2.1.x - see here: Bruno Santos Blog about libOpenSMOKE...

How to use dynSmagorinsky model correctly ?

This is a good reference for why not to use upwind schemes for LES

I'll try to give you some information of why central schemes are generally preferred in LES and then
