Hello everyone,I am trying to simulate one geometry (as attached 1)made  of composite material. For making the geometry i simply use the extruded boss and  extruded cut features. when i go for modelling composite i use "define shell by selecting faces" command . but by this way only faces are becoming composite(attached 2) but i want make the whole geometry as a composite material. It will be highly appreciated if anyone please help in this regards. Thank you.
