Go back to Day 4.

In this tutorial
- [https:// www.youtube.com/watch?v=lrGO9QSBq1g part 1]
- [https:// www.youtube.com/watch?v=pES0ybqs0cQ part 2]
we will cover one of the basic concepts in OpenFOAM. The resolution of your mesh might have an influence onto the results of your simulation. This [https:// www.youtube.com/watch?v=lrGO9QSBq1g video] gives you a feeling about the importance of grid resolution and how to avoid deviations caused by coarse grid resolution. We will cover
- field initialization with setFields
- mesh refinement with blockMesh
- simulation of a 1D shock tube case
- influence of mesh refinement on the simulation results
- postprocessing
