Notice: The authors acknowledge that naming conventions and input style formats for CalculiX are based on those used by ABAQUS, a proprietary, general purpose finite element code developed and supported by Hibbitt, Karlsson & Sorensen, Inc (HKS) (http://www.abaqus.com) and are used with kind permission from HKS. Results obtained from CalculiX are in no way connected to ABAQUS.

A discourse discussion group for CalculiX has been setup. That way you can share problems and experiences with other CalculiX users. To join the group go to https://calculix.discourse.group.
