Q: Can I find out the reactions between the bottom of a jacket and the ground during a deck mating?

A: If you believe that the jacket is a rigid body then the reactions are part of the analysis. To include the stiffness of the jacket you can do a "multi body" stress analysis:

   STRUCT

       &SELEC :B -SEL JACKET DECK

       LCASE -PROCESS T1, T2, .....

       BODSOLVE -BODY :B

   END

This will consider the stiffness of the jacket but not any dynamics of the elements in the deck and jacket.
