Go back to Day 2.

Grid convergence

In this 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 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
  • post processing
