I exported all forces (using: AnyMechOutputFileForceExport) for Pevis Segment
and Sacrum Segement (Main.HumanModel.BodyModel.Trunk.SegmentsLumbar.SacrumSeg) separately
I noticed that force "GluteusMaximusInferior" is included in both exported (.txt) files!!
In the .txt file based on PelvisSeg, it has a RefFrame
However, in the .txt file based on SacrumSeg, it has a different RefFrame
What is the difference between both values and which one to consider in the FEA?!
