Keywords: Video tutorial, CFD, About OpenFOAM, Solvers , Parallel Processing
| Visual Cue | Narration |
| Slide 1 | Hello and welcome to the spoken tutorial on Introduction to OpenFOAM. |
| Slide 2: About OpenFOAM | * OpenFOAM stands for Open source Field Operation And Manipulation.
|
| Slide 3: About OpenFOAM | A CFD tool box written in C++ and working on Linux operating systems. |
| Slide 4: About OpenFOAM | * OpenFOAM has an Object Oriented Programming Interface.
|
| Slide 5: OpenFOAM capability | OpenFOAM is a Finite Volume based CFD software using both structured and unstructured grid. |
| Slide 6: Mesh Generation | * OpenFOAM has a mesh generation tool called as blockMesh.
|
| Slide 7:Importing Mesh Files | * We can import mesh files from third party softwares like fluent, cfx by using these commands.
|
| Slide 8: Boundary Conditions | * There are various default boundary conditions which are available.
|
| Slide 9: Solvers | There are wide range of solvers available for: * Incompressible flows such as icoFoam
|
| Slide 10: Solvers | Users can create their own solvers or they can modify the existing solvers |
| Slide 11: Parallel Processing | * Parallel processing is easy in OpenFOAM and supports OpenMPI.
|
| Slide 12: Post-Processing | * OpenFOAM results can be visualized using Paraview.
|
| Slide 13: Equivalent to Commercial softwares | * Commercial softwares are costly.
|
| Slide 14: Modelling in OpenFOAM | Solver syntax in OpenFOAM is similar to that used in writing a Partial Differential Equation. |
| Slide 15: OpenFOAM code | For example, Analytically Momentum Equation is written as shown.
Shown below is the OpenFOAM code equivalent for this equation |
| Slide 16-22: OpenFOAM Results | We will now see some OpenFOAM applications-* Dam break simulation
OpenFOAM spoken tutorial are available on the spoken tutorial website. |
| Slide 23: About the Spoken Tutorial Project | * Watch the video available at this URL.
|
| Slide 24: About the Spoken Tutorial Project | The Spoken Tutorial Project Team
-Conducts workshops using spoken tutorials -Gives certificates to those who pass an online test -For more details, please write to contact@spoken-tutorial.org |
| Slide 25: Spoken tutorial Workshops | * Spoken Tutorials project is a part of Talk to a Teacher project.
