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
