Free Autodesk Meshmixer Strength Analysis tool

I was playing around with the free Autodesk Meshmixer to make some overhang supports. I cannot seem to ever get the supports the way I want them in this software. At any rate I came accross this strength analysis tool and had not thought about adding a weld to that vertical holder on an effector I am redesigning until seeing this visual. To use this feature, I imported the STL file, clicked Analysis button/Strength & turned on Show Sections. I attached a before & after the weld photo.
