Cantilever beam size optimization

jakub.ziontek

Hi, I would like to optimize cross section of cantilever beam. I have beam L=100, cross section is square h and b (1<b<10 and 1<h<20), and in the end we have 2 forces Y and X direction.
How can i run it in optistruct? I wanted by size optimization, but if I mesh it by shell i can optimize only one direction (one thickness). If i build solid beam how to do it? By shape optimization? I want t keep the same shape but change b and h to find solution. I have also allowable value of tip displ and yield strengh max value.

 

regards
Jakub
