Fluent to Tecplot - 3D slice Velocity Magnitude

Posted January 30, 2012 at 13:09 by emmkell

Just found a solutioin to my problem from another thread on the forum (thanks fremdar!)

I thought i'd post it here anyway in case anyone is having a similar problem:

Export a CGNS-file (selecting Velocity magnitude for me) from Fluent

Open the CGNS file using the CGNS Loader in Load data files option in tecplot.

ParaView 3.12.0 SuperBuild on OpenFOAM

<-- Related issues to ParaView with OpenFOAM - Fixes and solutions

Beginning with ParaView 3.12.0, a new method for building every single package that ParaView needs can be done via "SuperBuild", which is a sub-folder in the ParaView source code structure. The idea is simple:
  1. Run:
    or similar, such as ccmake or cmake-qt-gui.
  2. Choose the "ParaVIew-3.12.0/SuperBuild" folder as the source code and pick some other folder as the folder for the building

Find & Replacement & Delete

Posted January 19, 2012 at 12:13 by lakeat (Daniel Wei's CFD Blog: (

Here are some tips, to show that linux is really very powerful, once you know how to use it.

If you want to find or replacement, you dont need to open an editor, gedit, or vi. You can just simply do the following (choose one).
Why not just vi and :%s....? Because, the following command can be implemented in a shell scripts, so once you have dozens of files to operate, this is the better way.

perl -e "s/old_string/new_string/g"

Dark side of Amdahl's law. Epilogue

Dependence of efficiency on the number of cores is a very important characteristic of scalability solver based on which one can predict the scaling limit. For simplicity we consider only one option for the solver, using the asynchronous version of the MPI exchanges Isend() + Irecv(). It is seen that the dependence of the efficiency of parallelization of the solver is linear or nearly linear, with a gradual drop in effectivity with increasing number of cores used
