- Mapdl.psdspl(tblno='', rmin='', rmax='', **kwargs)#
Defines a partially correlated excitation in a PSD analysis.
APDL Command: PSDSPL
Input PSD table number defined with PSDVAL command.
Minimum distance between excitation points which are partially correlated. Excited nodes closer than RMIN will be fully correlated.
Maximum distance between excitation points which are partially correlated. Excited nodes farther apart than RMAX will be uncorrelated.
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.
