Hello all,



I am very much a beginner to CFD, and would like to know if there are any resources I can read for a more in depth explanation of OpenFOAM boundary types.


For example, what exactly is a patch? How does it behave when experiencing varying levels of pressure?


And how does the boundary type of patch differ from a boundary type of wall?


I'd be grateful if anyone can point me in the right direction. Thank you!

Hello,

Before anything else, read the manual and run the cases presented there. You will learn a lot from that. To your question, read the mesh section of it. You will learn that a patch is group of faces having the same functionality.
Try looking in the source code online as it has links to every entity of it. It will take a while to get used to it but in the end you will see the light. You don't need to understand everything there or know c++ to move things around.
Give it a try and be patient.
