Visual Cue Narration
Slide 1 Hello and welcome to the spoken tutorial on Importing Mesh files in OpenFOAM
Slide 2 : Learning Objectives In this tutorial, you will learn how to:
  • import Mesh files
  • from a meshing software
  • in OpenFOAM.
Slide 3  : Pre-requisite As a pre-requisite, the user should know how to generate a Mesh in software

like -Gambit, Ansys ICEM , CFX, Salome etc.


Slide 4: System Requirement To record this tutorial I am using
  • Linux Operating system Ubuntu version 12.04.
  • OpenFOAM version 2.1.1
  • ParaView version 3.12.0
Slide 5:. Using blockMesh, we can easily make simple geometries.

For example- pipe, box, etc.

Narration, no visual cue It is difficult to create complex geometries using blockMesh.

But OpenFOAM supports importing mesh from third party meshing software.

There are commands available in OpenFOAM, to import these mesh files.

We will now learn how to import these files

Slide 7 : geometry for the case 
Point over the square cylinder
point over its length and height
point on inlet velocity


Here is the geometry of our case.

We have a square cylinder

  • length 1m and height 1m.
  • Inlet velocity is 1 m/s
  • We are solving this for a Reynolds Number (Re) = 100
  • The domain chosen is 40 by 60
  • The Boundary conditions are as shown in the diagram
Slide 8 : This is the mesh file generated in a meshing software
Go to the OpenFOAM > xyz-

2.1.1>run>tutorials>incompressible >icoFoam

In your OpenFOAM working directory,

go to the icoFoam solver and click on it
