Use the force_upd_assem_mp_in_simp_rep configuration option to control the update of top-level assembly mass properties according to simplified representation definitions.

Set the configuration option to use_stored to calculate or not calculate mass properties according to mass properties accessible for all components in the subassembly.

Set the configuration option to yes to reflect simplified representation definitions in mass properties calculations.

Set the configuration option to no to disregard simplified representation definitions and perform all mass property calculations on the top-level Master representation.
