Hello everyone, I have available the outer surface of a shaped shovel with shell elements and should specify a thickness of 3mm starting from the surface, towards the inside (the section is a naca profile of 86mm rope). However in shells, when specifying a thickness t, this is applied t/2 in the direction of normal and -t/2 in the opposite direction. the shovel is subject to inertial load, being in rotation.
How can I do that? I found this option only in the shell91 element: in the parameter k11 "node offsets" you can specify the option "nodes@top".
However I do not understand if this option simply moves the knots from the midsurface to the top or effectively creates the thickness from the topsurface going in the opposite direction to the normal.
do you know if you can create the entire thickness towards the inside using another shell element?
Moreover, in the restrictions of the element I have read that inertial loads are not counted in case a node offset is specified. Do you know anything about that?
Thank you.
