hfang

SpecialPurpose.hfang(lab='', phi1='', phi2='', theta1='', theta2='', **kwargs)

Defines or displays spatial angles of a spherical radiation surface for sound radiation parameter calculations.

Mechanical APDL Command: HFANG

Parameters:

labstr

Spatial angle label.

• ANGLE - Define spatial angles (default).

• STATE - Display spatial angles. PHI1, PHI2, THETA1, and THETA2 are ignored.

phi1str

Starting and ending ϕ angles (degrees) in the spherical coordinate system. PHI1 defaults to 0 and PHI2 defaults to 360.

phi2str

Starting and ending ϕ angles (degrees) in the spherical coordinate system. PHI1 defaults to 0 and PHI2 defaults to 360.

theta1str

Starting and ending θ angles (degrees) in the spherical coordinate system. THETA1 defaults to 0 and THETA2 defaults to 180.

theta2str

Starting and ending θ angles (degrees) in the spherical coordinate system. THETA1 defaults to 0 and THETA2 defaults to 180.

Notes

Defines or displays spatial angles of a spherical radiation surface.

Use this command only with plfar, Lab = PRES, or prfar, Lab = PRES.
