In this [https:// www.youtube.com/watch?v=lrGO9QSBq1g tutorial] 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
