... the design is 'checked' by multiple structural simulations .. what does
'checked' mean here?
... cannot be formulated by 'Explicit functions' ... what do you exactly
mean? Are equations implicit or just no equations?
If you have equations, i should be able to help. Show some equations in
your reply.
Thanks,
Phil
