Boundary conditions for the group of patches

Roman1 · November 5, 2013, 14:31

Hello everybody. Please help with resolving next problem. I use a OF case that includes very many different geometry objects, mostly boxes. Writing boundary conditions for each of them takes much time and much "paper". They all have the equal BC. Is there a method of assigning one and the same BC to a group of patches or walls (to a list of patches or to all together) ? Thanks.

Good evening Roman,

You want to look into the use of regular expression for the naming of the boundaries. A good example for this is the motorBike tutorial, which you can find here (for OF2.2.0):

OpenFOAM-2.2.0/tutorials/incompressible/simpleFoam/motorBike

Good luck,

Niels
