I am wondering how Karamba’s optimize cross section component works when dealing with an indeterminate system. As I understand it the component simply picks the first beam that works in the specified list, but in an indeterminate system the load to each member will vary based on it’s stiffness. If the cross section changes, so does the load to the beam, and this becomes an iterative process that the component does not perform if I am understanding it correctly. Is there a better way to define an optimal cross section, maybe without the optimize cross section component but with galapagos instead?
Thanks in advance.
