Comments
CYSYM and CYJOIN Bulk Data Entries are required in cyclic
symmetry analysis.
Supported analysis types include
linear static (STATIC) and normal mode analysis (MODES). For normal mode
analysis, currently only Lanczos (EIGRL) and Lapack-based
dense (EIGRD) solvers are supported.
SPC and MPC references in the
subcase section are required to be consistent for all subcases in cyclic
symmetry analysis.
The modeled segment is defined as
the basic segment with index of 1. The rest of the segments are numbered
following the right-hand screw rule, where the thumb points in the positive
direction of the axis and the segment indices are defined sequentially in
the counter clockwise order. Figure 1
