FAQ
ParticipantSymmetry boundary condition is used to enforce mirrored symmetry on one or more faces in the same plane. In fluid physics, this creates a free-slip, insulated wall that mirrors the flow pattern on both sides.
In the following video, we will focus on how the symmetry condition can be used for fluid simulations. Keep in mind, symmetry is only applicable to flat faces and can be applied to multiple faces on the same plane.
- For solid-thermal physics regions, the symmetry condition creates an insulated wall to mirror the expected pattern of the thermal solution on either side of it.
- For a structural physics region, the symmetry condition creates a support normal to the face.
- For a topology optimization simulation, the symmetry condition ensures that the model is dimensionally reduced based on a mirror plane. Note that the protected distance on the symmetric surface is set to zero.
