Baffles01 - createPatch & createBaffle

Posted July 21, 2018 at 11:48 by student666
Updated September 22, 2018 at 12:52 by student666

Objective: test cases for using following dicts:
  • createPatchDict
  • createBafflesDict

Preliminary steps:
  1. Run the Salome script for the geometry and surface mesh generation
  2. Export walls, inlet outlet inside cad/stl as STL (ASCII)
  3. Run the utility buildRegionSTL, it will create the constant/triSurface folder with buildRegionSTL.stl
  4. Export the interna mesh as interna.stl inside constant/triSurface

************Set up the SHM dict file for create Patch (highlights)...

Lognormal Distribution for Particle Size in OpenFOAM

Posted May 1, 2018 at 11:13 by Mehar

This is for future reference, if anyone wants to use lognormal particle distribution in OpenFoam.
1) Generate PDF from following formula


Here mu and sigma are the geometric mean and standard deviation of the particle size distribution
Here is an example plot of the lognormal distribution with mean 1 and standard deviations of 1.8, and 3. You can first re-create lognormal distribution with these parameters...

Meshing with Solome for OpenFOAM

Posted January 26, 2018 at 15:13 by makaveli_lcf (test)

So I have started to study Salome for the drawing and meshing geometries for the OpenFOAM applications.

It is very easy tool to create geometries, in my case first try was continuous casting mold with a submerged entry nozzle.

Meshing order

  1. Mesh the edges, especially feature edges
  2. Mesh faces with the transition from smaller elements near the features to bigger ones away from them (where it is actually needed)
  3. Mesh the rest of the volume mesh

Generating Surface Stream Lines with Paraview (From 3D data)

Posted May 26, 2015 at 05:18 by Mehar

Being a Newbie, I have struggled to add surface streamlines to a slice, as I cannot find Appropriate instructions on this...However, after a long time struggle, I am able to add surface streamlines to a slice, which I would like to share with other newbies to avoid that head ace!

Following is the step by step procedure for generating surface streamlines!

1. Load Your Data in paraview
2. Add Slice filter to your Loaded Data
3. Add SurfaceVector filter...
