Preserve Mass Distribution during Scaling

[Michael Heil]

Hi,

is it possible that preserve mass distribution works exactly the other way around as described in the User's Guide (https://simtk-confluence.stanford.edu/d ... ling+Works) when Target Mass > 0 ?

I tried the four different options on a simple model that only consists of two bodies and checked the results with a manual calculation. The results, I manually calculated for the case "TM > 0, PMD is checked" according to the description, are the results that OpenSim calculates for the case "TM > 0, PMD is unchecked" and vice versa.

It would be great if someone looked into this issue.

Thanks,

Michael
