The latest SysMLHelper package (4.3.b.Release) is now available on Github. This is an open-source profile and helper collection. The ExecutableMBSE profile part of this as well as providing a Harmony/SE like approach includes function block and function chain modeling enhancements using advanced profile features of Rhapsody. It works with 8.3.1 upwards.
