18 Aug Choosing boundary conditions
Sometimes CFD and FEM simulations can really be hard to complete. If you are un-experienced, you may find some of the basic tricks of this type of analysis quite difficult to understand. In these situation please don’t panic: there are very simple operation to accomplish to obtain an impressive result. One of these operation is understanding the meaning of boundary conditions. As usually in these situation a practical example can really help you understanding what is happening.
Once you have created all the face groups required for your peculiar case you can proceed with the mesh generation and, finally the CFD settings. In this stage you are required to impose a peculiar behaviour on every face defined during the GEOMETRY step. This behaviour is nothing else than the physical representation of the boundary itself: inlet, outlet, wall, etc. So think logically: just consider what is happening though that surface and find the boundary type that best represent this. CONSELF in fact gives you a number of pre-configured boundary conditions to apply to your geometry (check our manual to discover them!).
