NX Nastran DMAP Programmer's Guide - Kxcad.net

Parameters:
DDRMM
Performs matrix method data recovery
OPTION Input-character-default='ABS'. Response summation method for
scaled response spectra analysis only. Possible values are:
'ABS' absolute
'SRSS' square root of the sum of the squares
'NRL' Naval Research Laboratory (new)
'NRLO' Naval Research Laboratory (old)
NOCOMP Input-integer-default=0. Set to 3 if IES is element strains.
ACOUSTIC Input-integer-default=0. Fluid-structure analysis flag.
PEXIST Input-logical-default=FALSE. Set to TRUE if p-elements are present.
0 No fluid elements exist.
1 Penalty or fluid acoustic elements exists.
2 fluid/structure coupling exists.
ACOUT Input-character-default='PEAK'. Type of acoustic pressure output in
fluid-structural analysis.
'RMS' root-mean-square
'PEAK' peak
PREFDB Input-real-default=1.0. Peak pressure reference for pressure level in
units of dB or dBA.
SEID Input-integer-default=0. Superelement identification number.
Remarks:
1. If UD is a real matrix and OL is purged, then a scaled response spectra analysis is
assumed.
2. OUG, OQG, OES, and OEF are suitable for printing or punching by the OFP
module.
3. SDR2 is used to compute IUG, IQG, IES, and IEF, which are results due to a unit
modal displacement (eigenvector).
