ANGLE

Phase angle (degrees) for expansion pass. If ALL (default), use both 0.0° (real) and 90.0° (imaginary) phase angles.

Notes

Specifies the phase angle where the expansion pass will be done for a harmonic mode-superposition expansion pass.

For a specific angle, the following real solution is stored in the results (*.rst) file:

Where:

i is the degree of freedom number.

is the amplitude of the i th degree of freedom solution

Φi is the phase shift angle of the i th degree of freedom solution

ϕ is the supplied phase shift angle (ANGLE)

If ANGLE is ALL, both the real and imaginary parts of the solution are stored in the results file.

For more details about the solution equations, see Harmonic Analyses in the Mechanical APDL Theory Reference.

This command is ignored if the HROPT command has been issued with Method = VT or Method = VTRU.

This command is also valid in PREP7.
