Hello everyone, can anyone tell me if changing the mass of a body via XML, for example hand, is it possible to analyze and plot graphics with this mass in kg?

Hi Lisias,

You definitely can change the value of the mass in XML for any Body/Segment in the model. For units, a Model has a "getLengthUnits()" and a "getForceUnits()" that allow you to retrieve the units of the model. These also show in the Properties window when a model is selected in the OpenSim application, internally these are Meters and Newtons respectively.

Hope this helps,
-Ayman

Thank you!

By changing the mass of a body is it possible to see changes in the graphs plot?
