porous solid modeling in abaqus

Hello every 1

I must model porous materials in abaqus!!but really i am confused how to create these complex shapes :p:p:p

voids in my models are not arranged but i thinks that i have to model them regular,how ever i need to simulate an configure like bone structure(specially that some wheres in model have more voids or less some thing like bone)

by the way my models are 3D and thickness of trabeculae|(pores wall) in configure is not constant(just like bone!!):cool:

thanksto all:)
