How to setup physics with many faces

    • seffa

      I have a complex geometry with around 800 faces. The Physics task requires I set a boundary layer to all of them. Is there a way to just auto-assign all the faces to walls?

      Hi seffa

      Once you setup a fluid flow problem, an automatic BC named "Wall Boundary" is added under fluid flow conditions. All faces in your model are being designated as a wall to begin with. As you further add inlet and outlet conditions to some faces, the wall BC appropriately updates itself automatically, and omits the surfaces used in these user defined  BCs. This is how the condition is met and all surfaces in the model have some or the other boundary condition assigned it.  User just needs to  scope few surfaces for user defined BCs and the rest is taken care by the wall.

      In case your model is not showing the default wall BC by any chance (or you have deleted it by mistake), just add another wall BC from "Fluid flow conditions" and it will automatically use all the surfaces, which haven't been assigned any BC so far, as wall surfaces.

      I hope that solves your problem.

      Thanks & Regards,
