Softbody simulation

Hi @kellyg,

Thanks for your reply regarding this matter. As a matter of fact, I tried to scale the mesh as you suggested, however, it seems like scaling the mesh actually affects the behavior of the deformation. As shown in the figure below, when running the code soft_body.py and left it running for 20 seconds or so, the default scale works as expected but with scaled mesh, the object seems like deforms itself. After awhile the shape of the ball changes completely. Should I modify anything else like density to make it work? It would be nice to get a hint to solve this. I have been stuck with it for quite some time :D. Thanks in advance!
