SEMA
Assembles square symmetric matrices from upstream superelements
SEMA Assembles square symmetric matrices from upstream superelements
Assembles square symmetric matrices (e.g., stiffness, mass, damping) from upstream
superelements into the current superelement.
Format:
SEMA BGPDTS,SLIST,SEMAP,XJJ,XAA*,MAPS*,GDNTAB/
XGG/
SEID/LUSETS/QUALNAM/UPFM $
Input Data Blocks:
BGPDTS Basic grid point definition table for the current superelement.
SLIST Superelement processing list to matrix generation, assembly, and
reduction.
SEMAP Superelement map table.
XJJ Square matrix for the g-set of the current superelement and applied to
its interior points only.
XAA* Family of reduced square matrices in a-set pertaining to the upstream
superelements.
MAPS* Family of MAPS (superelement upstream to downstream boundary
coordinate system, secondary (mirror, identical, and repeated), and
release transformation matrix).
GDNTAB Table of grid points generated for p-element analysis.
Output Data Block:
XGG Square matrix in g-set including contributions from upstream
superelements.
Parameters:
SEID Input-integer-default=0. Superelement identification number.
LUSETS Input-integer-default=0. The number of degrees-of-freedom in the
g-set of the current superelement.
QUALNAM Input-character-default='SEID'. Name of qualifier to be used in
selecting MAPS and PA.
UPFM Input-integer-default=0. UFM 4252 print flag. Set to -1 to print UFM
4252 and set NOGO=-1 if there are missing upstream boundary
matrices.
