Reply To: Difference between acceleration probe and directional acceleration

[peteroznewman]

I didn't say the probe shows only relative acceleration, I said it can show relative acceleration if a joint is created between two moving objects.  It can also show absolute acceleration if a joint is to ground for example.  Since you provided no context in your original post, I wanted to cover that possibility.

I expect that the probe provides the acceleration of the center of mass of the rigid body, while the directional acceleration provides the acceleration of the corners of the rigid body.

In my model, I used a Flexible body for the mass, not a rigid body. When I request a probe, I get a Spatial Resolution field where I can choose either Use Maximum or Use Minimum.
