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. It is an Open Source Computational Fluid Dynamics Software.
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. It is licensed under GNU General Public Licence.
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. It is used for structured meshing, small and easy grids. Mesh input is in form of a script and no GUI. It also has an Advanced Meshing tool called as snappyHexMesh.
Slide 7:Importing Mesh Files	* We can import mesh files from third party softwares like fluent, cfx by using these commands. This is useful for large and complex grids. We can also use arbitrary polyhedral mesh.
Slide 8: Boundary Conditions	* There are various default boundary conditions which are available. Users can modify the existing boundary conditions according to their case.
Slide 9: Solvers	There are wide range of solvers available for: * Incompressible flows such as icoFoam Compressible flows such as sonicFoam Multiphase flows such as interFoam, Combustion - chemFoam, Particle-tracking flows - coalChemistryFoam, Molecular Dynamics - mdFoam and MHD flows and many more.
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. We can use 'n' number of processors.
Slide 12: Post-Processing	* OpenFOAM results can be visualized using Paraview. OpenFOAM data can also be visulalised in softwares such as Tecplot, Ensight , and etc.
Slide 13: Equivalent to Commercial softwares	* Commercial softwares are costly. Source code is not available. Solver capabilities of OpenFOAM are as good as Fluent, CFX, Star CCM +, etc.
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 Moving Reference Frame simulation Arbitrary Mesh Interface Ship Propeller Simulation 3D Bluff body simulation Particle-tracking 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. It summarizes the Spoken Tutorial Project. If you do not have a good bandwidth you can download and watch it.
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. It is supported by the National Mission on Education through ICT, MHRD, Government of India. This project is coordinated by http://spoken-tutorial More information on this mission is available at the following URL link http://spoken-tutorial.org/NMEICT-Intro
