RANDPS

Bulk Data Entry Defines load set power spectral density factors for use in random analysis having the frequency dependent form $S_{jk}\left(\Omega \right)=\left(X+iY\right)G\left(\Omega \right)$ .

Definitions

Field	Contents	SI Unit Example
SID	Random analysis set identification number. (Integer > 0)
J	Subcase identification number of excited load set. (Integer > 0)
K	Subcase identification number of applied load set. (Integer > 0; K ≥ J)
X, Y	Components of complex number. (Real)
TID	A TABRNDi entry identification number which defines G(F). = 0 G(F) = 1.0 Integer ≥ 0

Comments

1. If J = K, then Y must be 0.0.
2. RANDPS Bulk Data Entries can be referenced either by:
   • The RANDOM Subcase or Case Control Entry.
   • A SET I/O Options Entry that is then referenced by a RANDOM Case Control Entry.
   • A SET Bulk Data Entry with TYPE=MODE that is then referenced by a RANDOM Case Control Entry.
