  Hello Rex,
  Could you give us more details and show an image of your rotating object? What is making the object rotate? For example, if you have a ball attached to a string going in a circle, the centrifugal force would be equal to the tension in the string.

    I set an axial constraint on the top of the red object and rotate it clockwise at high speed. I want to know the centrifugal force of the red object.

  Hello Rex,
  Do you have a contact between the red and blue parts? If so, you could post-process the contact force in the normal direction between the 2 bodies to get what you want.
