One simple way to get the center point is to average the x, y, and z coordinates of that surface. That should give us the center point. 1. Go to Report->Surface Integrals 2. Select Mesh under Field Variables 3. Select X-coordinate under Mesh 4. Select the surface under Surfaces 5. Select Area-Weighted Average under Report Type 6. Click on Compute Repeat the above for y-, and z-coordinates. That should give you the center point.
