Welcome to Day 5. After some dry topics, today we have some fun simulations for you.

Go back to "3 weeks" series.

Running your first case on your own

As a start try your gained knowledge about OpenFOAM and set up a case on your own. For this you will need everything you have learned so far. You will cover

  • creating your mesh
  • setting up initial and boundary conditions
  • setting up physical properties
  • setting correct numerical settings
  • running your simulation
  • postprocessing your simulation

Hagen Poiseuille flow

Another fun simulation is the laminar Hagen Poiseuille flow. Follow the set-by-step introductions to utilize and further extend your gained knowledge about

  • a simple case setup
  • function objects
  • laminar flow
  • numerics
  • sampling during postprocessing

Tips and Tricks for OpenFOAM simulations

Below you will find additional material, where you can find tips and tricks for the improvement of your simulation. Feel free to go though them and fall back to them in the future, once you encounter some problems in your simulation.
