How can the number of BEAM SECTION cards be reduced for ABAQUS output?
Answer: Use the vector option to define the orientation of the local coordinate system of the cross section of the beam. Then use the ztol command with a tolerance of, perhaps, .0001 to compensate for numerical errors.
This is needed because the
TrueGrid®'s
internal data structure for a beam includes
its orientation point (not vector). When the output file is written for ABAQUS,
TrueGrid®
converts the points to vectors, and sorts them to get a unique list. This
can be the source of numerical errors, and is the reason for the need for the
tolerance parameter.
