Description: When the model of a single part contains both shell and solid sections, such as when a midsurface shell section is created within a solid part, Abaqus/CAE now automatically creates shell-to-solid coupling constraints so that the shell portions of the model follow the motion of the adjoining solid sections.

Automatic shell-to-solid coupling constraints are created only in sections within the same part instance, and the sections being constrained must be nearly perpendicular. You must manually create shell-to-solid coupling constraints between separate part instances.
