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:
|
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
|
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
|
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 |
Create a folder : cylinder | Create a folder by the name cylinder |
Type cd (space) .. | Go one level back |
Copy 0 and system folder from
cavity folder in icoFoam |
Copy the 0 and system folders from the cavity case. |
Paste it in cylinder folder | Then paste it inside the cylinder folder. |
No constant folder | Note that you do not need the constant folder. |
Point over the .msh file on the
desktop |
On my desktop, I have a Fluent mesh file with a .(dot) msh extension
It is named as cylmesh.msh |
Copy-and-paste >> cylinder folder. | Copy-and-paste this file in the cylinder folder in icoFoam.
Our setup is now ready |
Ctrl+Alt+t keys simultaneously | Open a command terminal and press Enter. |
In the terminal window >> type run >> press Enter. | Type run and press Enter.
