Hi,
please see attached model where I am trying to creat a polygonal surface element with a polygonal meshing.
i have following queries:
1. once i have created the surface and then meshed it then staad divides it into various plates. now in order to assign properties can i use plate thickness?
2. when to use surface thickness option? i.e. if staad is going to divide the meshed surface into plates then what's the point of having availability of surface thickness option?!!
3. once created the surface I tried to model a random polygonal opening into surface but struggling to do that. please advise. do i need to create another surface within polygonal profile for hole and then define a second surface as hole?!!
4. the stress types on surface -are they only membrane or plate ie. including across thickness bending (as staad divides surface into plates anyways)!
thanks.
