PRESOL
Prepares special tables for the distributed parallel solution
PRESOL Prepares special tables for the distributed parallel solution
Prepares special tables for the distributed parallel solution using the domain
decomposition method.
Format:
PRESOL GEQMAP,USET,SIL,PARFIL,PFA,PJXL/
EQMAP,GAPAR,PARTF,PFA1/
UNUSED1/UNUSED2 $
Input Data Blocks:
GEQMAP Table of grid based local equation map indicating which grid resides on
which processors/partitions for domain decomposition.
USET Degree-of-freedom set membership table for g-set.
SIL Scalar index list.
PARTVEC Partitioning vector with values of 1.0 at the rows corresponding to
degrees-of-freedom that are locally constrained.
PFA Static load matrix with partial boundary loads in the a-set.
PJXL Static load matrix for boundary load contribution from the residual
structure.
Output Data Blocks:
EQMAP Table of degree-of-freedom global-to-local maps for domain
decomposition.
GAPAR Partitioning vector which is used to partition the local a-set
displacements from the global a-set displacements. It contains a 1 at
each row which does not have a contribution from the current processor
and zero if it does.
PARTVEC1 Updated PARTVEC indicating for all constraints; local and boundary.
PFA1 Updated PFA with complete boundary loads.
Parameters:
Unusedi Input-integer-default=0. Unused and may be unspecified.
