Center of mass (X,Y,Z coordinates) for complicated domain but with isotropic density

Please login with a confirmed email address before reporting spam

Background: I am modeling an elbow joint and I need to scale two bones equally so they almost touch.

Problem: If I am not mistaken, there is no offset surface command in COMSOL. However, the "scale" transform should work. The problem is, in order to scale appropriately, I need the coordinates for the center of the domain to input as the "Center of Scaling."

Solution: Is there a way to find the X,Y,Z coordinates of the center of the domain? I was thinking of using the built in "integration" to find the center through volume integration and the moments in the XY, XZ, and YZ planes. I am having trouble going about that though and I would appreciate some pointers. Thanks so much!
