Welcome back to Day 4. Today we will go even further into the depths and find, where the rubber meets the road (at least mathematically). We will have a special focus on discretization. Why is this important? Did you ever try to solve the fluid dynamic equations for an arbitrary industrial application by hand? Well... In most cases it is a better idea to break down the partial differential/integral equations into "simple" operations (+,-,*,/). This is called discretization. Today you will gain the knowledge, how this works.
We will concentrate on:
Go back to "3 weeks" series.
Theory
In this tutorial you will find an in depth explanation of the theory in CFD and also in OpenFOAM. A brief summary of the topics covered:
- finite volume method
- CFL number
- linear solvers
- solution methods
- unsteady and steady simulation
- residuals
- boundary and initial conditions
