Freely Adjustable Wind Permeability for Surfaces

Use RWIND 2 Pro to easily apply a permeability to a surface. All you need is the definition of

  • the Darcy coefficient D,
  • the inertial coefficient I, and
  • the length of the porous medium in the direction of flow L,

to define a pressure boundary condition between the front and back of a porous zone. Due to this setting, you obtain the flow through this zone with a two-part result display on both sides of the zone area.

But that's not all. Furthermore, the generation of a simplified model recognizes permeable zones and takes into account the corresponding openings in the model coating. Can you waive an elaborate geometric modeling of the porous element? Understandable – we have good news for you then! With a pure definition of the permeability parameters, you can avoid complex geometric modeling of the porous element. Use this feature to simulate permeable scaffolding, dust curtains, mesh structures, and so on.
