Attach sensor points to moving body
 

Hi! I'm simulating 2d box falling into water, using 6DOF solver and VOF multiphase model. I want to specify some sample points under the bottom of the box(moving mesh), in order to get the pressure history at these points when the box impacts with water surface.
How can I define these points? Do I need to use UDF to specify them?

Thanks!

Is there any suggestion for me?
Thanks!
