spfreq

SpectrumOptions.spfreq(tblno='', freq1='', freq2='', freq3='', freq4='', freq5='', freq6='', freq7='', **kwargs)

Defines the frequency points for the input spectrum tables spval vs. spfreq for multi- point spectrum analysis.

Mechanical APDL Command: SPFREQ

Parameters:

tblnostr

Input table number. Up to 200 tables may be defined.

freq1str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq2str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq3str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq4str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq5str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq6str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

freq7str

Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must be in ascending order.

Notes

The spectrum values are input with the spval command. A separate spfreq command must be used for each table defined. Frequencies must be in ascending order.

Repeat spfreq command for additional frequency points. Values are added after the last nonzero frequency.

If all fields after spfreq are blank, all input vs. frequency tables are erased. If TBLNO is the only non-blank field, all corresponding spval curves are erased.

Use the sptopt and stat commands to list current frequency points.

This command is also valid in PREP7.
