# Symmetry Surface

BC_Type = SymmetryBC: This boundary condition is used at the symmetry surfaces. HyperXtrude imposes zero normal velocity at these planes.

Syntax for this boundary condition is:

SymmetryBC Boundary_Name { }

If the elements on this BC lie on a single plane and you know the components of the normal in x, y, and z, you can specify this value.

SymmetryBC Boundary_Name {

Nx = component of normal in x direction

Ny = component of normal in y direction

Nz = component of normal in z direction

}

For example, if the face is in yz plane and the boundary is called sym_yz then

SymmetryBC sym_yz {

Nx = 1.0

Ny = 0.0

Nz = 0.0

}
