INSFVSymmetryVelocityBC
This object implements a symmetry boundary condition for the velocity. It applies boundary forces such that the gradient of the velocity parallel to the boundary is zero in the boundary normal direction. A INSFVSymmetryVelocityBC should be applied for every velocity component on a symmetry boundary. Similarly an INSFVSymmetryPressureBC should be applied for the pressure on the symmetry boundary.
Input Parameters

Controllable:No
Description:The displacements
- prop_getter_suffixAn optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
C++ Type:MaterialPropertyName
Controllable:No
Description:An optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
- v0The velocity in the y direction.
Default:0

Controllable:No
Description:The velocity in the y direction.
- w0The velocity in the z direction.

Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form
- use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
Default:False
C++ Type:bool
Controllable:No
Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

# Note that for this model (using the wall-distance mixing length for the entire
# pipe) different von Karman constants are optimal for different Reynolds
