DDRMM
Performs matrix method data recovery
DDRMM Performs matrix method data recovery
Computes data recovery items (stress, displacements, forces, strains, forces) directly
from the modal solution in frequency response, transient response, or scaled response
spectra analysis using the matrix method.
Format:
DDRMM CASECC,UH,OL,IUG,IQG,IES,IEF,XYCDB/
OUG,OQG,OES,OEF,UNUSED5/
OPTION/NOCOMP/PEXIST/ACOUSTIC/ACOUT/PREFDB/SEID $
Input Data Blocks:
CASECC Table of Case Control command images.
EST Element summary table.
UH Solution matrix for the h-set (modal degrees-of-freedom). Modal
displacements only in frequency response. Modal displacements,
velocities, and accelerations in transient response.
OL Transient response time output list or frequency response frequency
output list.
IUG Table of displacements due to unit modal displacement in SORT1 or
SORT2 format.
IQG Table of single point forces of constraint due to unit modal
displacement in SORT1 or SORT2 format.
IES Table of element stresses or strains due to unit modal displacement in
SORT1 or SORT2 format. For strains, NOCOMP must be set to 3.
IEF Table of element forces due to unit modal displacement in SORT1 or
SORT2 format.
XYCDB Table of x-y plotting commands.
Output Data Blocks:
OUG Table of displacements in SORT1 or SORT2 format.
OQG Table of single point forces of constraint SORT1 or SORT2 format.
OES Table of element stresses or strains in SORT1 or SORT2 format.
OEF Table of element forces in SORT1 or SORT2 format.
UNUSED5 Unused and may be purged.
