In this

• [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
