This tutorial describes how to use enGrid in order to create a mesh with regions which is suitable to simulate conjugate heat transfer with OPENFOAM®'s chtMultiRegionSimpleFoam.
This tutorial should be considered as a starting point and as an invitation to try and improve it. For the beginning it isn't much more than a collection of screen-shots. Please try it and if you get stuck ask for help. If you succeed, we would be very glad if you could use your experiences to improve this tutorial! I find it very difficult to write a good tutorial for enGrid, because most things are obvious to me, because I wrote most of the software.The complete case with all meshing steps and the OPENFOAM® case set-up can be found here:
