Whether you are a beginner in modeling or you are a great modeler this course is going to be useful. This course is about breaking the modeling boundaries and be able to actually create any model you want to do. OpenFOAM allows us to program our own solvers and that’s what makes it special. Most of the modeling software have a set of predefined solvers that you need to stick with, but not OpenFOAM, you will have the predefined solvers along with the capability to create your own.
So in this course you will learn how to model using OpenFOAM and how to be able to create your solvers from the very beginning. I’m going to make it easy, simple and hopefully fun to follow my lectures ;)). All I guarantee to you is that you will find it useful at the end.
