Unit added for ASET Step in the StiffGen dialog for ease of use.
Settings and Modeling Tips
When using the StiffGen to generate ASET's, any previously created ASET-set must be manually commented out or deleted by the user, otherwise the number of ASETs will be larger then the number of modeling points.
Dynamic points are not intended for use in compliant moves, and a warning was added for the users.
Obsolete Features
The Spring method was removed from the CM routines.
Issues Fixed
Resolved the double selection of the nodes when using StiffGen to create nodes for DCS points on an external (Abaqus) mesh, issue.
