Connection between 3D and shell modelings

It is now possible to connect kinematically two portions of models having different modelizations (command AFFE_CHAR_MECA/LIAISON_MAIL/TYPE_RACCORD=’ MASSIF_COQUE’).

In the example below, a cracked cylinder is subjected to an axial traction. The cracked zone is modelized by volumetric elements and the remainder of the cylinder is modelized by DKT shell elements.
