6.1. HBM Expansion and Postprocessing Tips and Limitations

For non-cyclic solutions, a macro (HBM_EXPA.mac) is provided to expand the solution by combining harmonics. For a detailed description of the macro, see Appendix A: HBM Macros. The following example problems demonstrate usage of the HBM_EXPA.mac macro:

Example 2: Two Cantilever Beams with Frictionless Gap Contact

Example 3: Two Jointed Beams with Frictional Contact Interface

For cyclic solutions (HBMOPT,CYCLIC,CYCkey=1), the HBMCYCEXPAND macro can be used. The following example problems demonstrates usage of the HBMCYCEXPAND.mac macro:

Example 4: Cyclic Spring-Mass System with Cubic Nonlinearity

Example 5: Cyclic Model with Solid Elements and Frictional Contact
