GENTRAN
Generates a transformation matrix
GENTRAN Generates a transformation matrix
Generates a transformation matrix that will convert the upstream boundary
coordinate system to the downstream coordinate system.
Format:
GENTRAN SEMAP,BGPDTS,CSTMS,BGPDTD,CSTMD,SCSTM/
MAPS/
SEID $
Input Data Blocks:
SEMAP Superelement map table.
BGPDTS Basic grid point definition table for the current superelement.
CSTMS Table of coordinate system transformation matrices for the current
superelement.
BGPDTD Basic grid point definition table for the downstream superelement.
CSTMD Table of coordinate system transformation matrices for the downstream
superelement.
SCSTM Table of global transformation matrices for partitioned superelements.
Output Data Block:
MAPS Superelement upstream to downstream boundary coordinate
transformation matrix.
Parameter:
SEID Input-integer-default=0. Superelement identification number.
Example:
Excerpt from subDMAP PHASE0.
