May I ask how you use Calculix for composite analysis? Is there a good GUI to use on a .stp file or will it require high level coding? Also have you had any experience using code_aster for composites? Is it viable as a tool to model a small aircraft entirely made of composites? Mystran looks...

Hi all, I am trying to arrive on a tool to use for FEM of an aeronautical structure. My company is quite small and thus has a limited budget so we are trying to avoid software such as Nastran, Ansys, Hyperworks, etc So far the best I have found that allows for laminate modeling is Mecway using...

Hi SWComposites I am not sure tha'ts the correct approach in my current situation. I have calculated the ultimate load cases of the fuselage and have frozen baseline for it that i just need to be just need to be below failure. The fuselage has a complicated aerodynamic shape with several...

Hi All I am new to composite FEA and currently trying to build a full composite fuselage. I need to optimize if force weight and am currently struggling with finding any type of methodology to do so. Do you guys have anything that works wells for you? I try for example to create a laminate...
