      hi


      i just want to calculate the velocity of the pig tool (mentioned below) due to differential pressure. what is the mean of mesh x velocity and center of gravity velocity mentioned here?



      i used 6dof udf.

      Hi, 


      Center of gravity is CG for the rigid body selected. 


      Regards,

      i gave center of gravity velocity V_X 2.1m/s..


      is this only considered as that rigid body velocity while giving whatever the pressure/velocity given in the inlet? 


      can i run the simulation without giving this velocity?

      If you are using 6dof then you can run it without giving this velocity.

      6dof will compute moments and forces on the wall defined in 6dof settings.
