HFSYM

HFSYM, KCN, Xkey, Ykey, Zkey
Indicates the presence of symmetry planes for the computation of acoustic fields in the near and far field domains (beyond the finite element region).

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

KCN

Coordinate system reference number. KCN may be 0 (Cartesian), or any previously defined local Cartesian coordinate system number (>10). Defaults to 0.

Xkey

Key for acoustic field boundary condition, as prescribed for the solution, corresponding to the x = constant plane:

None

 — 

No sound soft or sound hard boundary conditions (default).

SSB

 — 

Sound soft boundary (pressure = 0).

SHB

 — 

Sound hard boundary (normal velocity = 0).

Ykey

Key for acoustic field boundary condition, as prescribed for the solution, corresponding to the y = constant plane:

None

 — 

No sound soft or sound hard boundary conditions (default).

SSB

 — 

Sound soft boundary (pressure = 0).

SHB

 — 

Sound hard boundary (normal velocity = 0).

Zkey

Key for acoustic field boundary condition, as prescribed for the solution, corresponding to the z = constant plane:

None

 — 

No sound soft or sound hard boundary conditions (default).

SSB

 — 

Sound soft boundary (pressure = 0).

SHB

 — 

Sound hard boundary (normal velocity = 0).

Notes

HFSYM uses the image principle to indicate symmetry planes (x, y, or z = constant plane) for acoustic field computations outside the modeled domain. A sound hard boundary condition must be indicated even though it occurs as a natural boundary condition.
