PSDSPL
PSDSPL, TBLNO, RMIN, RMAX
Defines a partially correlated excitation in a PSD analysis.
TBLNOInput PSD table number defined with PSDVAL command.
RMINMinimum distance between excitation points which are partially correlated. Excited nodes closer than
RMINwill be fully correlated.RMAXMaximum distance between excitation points which are partially correlated. Excited nodes farther apart than
RMAXwill be uncorrelated.
Notes
Defines a partially correlated excitation in terms of a sphere
of influence relating excitation point geometry (in a PSD analysis).
If the distance between any two excitation points is less than RMIN, then the excitation is fully correlated. If
the distance is greater than RMAX, then
the excitation is uncorrelated. If the distance lies between RMIN and RMAX, then the
excitation is partially correlated with the degree of correlation
dependent on the separation distance between the points. This command
is not available for a pressure PSD analysis.
This command is also valid in PREP7.
