Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.

Publishing and Reporting
Create, define, and export reports.

HyperMesh Comments

If you insert special comment cards into your input deck, you can provide HyperMesh with additional information about the colors and names of entities. You can also use comments to preserve information that is not supported by a particular solver, for example, assemblies or system references.

These comments are written to analysis decks by most HyperMesh templates.
