I'm trying to define a user define geometry in Abaqus SwiftComp GUI ( like section 3 of the manual) for homogenization like hexagonal pack, however after sketching and partitioning of it, when I try to choose the defined Section to assign it to fiber/matrix parts, it does not show any of previous defined Section, while I defined two for fiber and matrix. I tried to define a section at the same time of assigning it for solid, still doesn't work. Other sections work well like shell, beam, and other; but not the solid one. I do appreciate you check this with your software and inform me concerning this.
Many thanks for your time and consideration in advance!
