Description: [I am studying optistruct, and I am doing the analysis of a bracekt with center mass load. I add 2 loadsteps , one is normal mode, and the other is Gload. I found the mode analysis result would be changed per the Gload analysis type. If the Gload analysis type is non-linear static, the modes will be 145HZ…
Hi everyone! This should be a simple question: how can I create fastener vectors without geometry? My component is a curved panel with holes for fasteners. I’ve already inserted RBE2 elements with a central node at each hole. Now I want to create a line/vector/coordinate system normal to the surface at each hole. I found…
Hello, I have Question regarding the Calculation of Interaction Effects in Hyperstudy 2024.1. I ran a fractional Factorial Screening DOE with Resolution IV, with 10 Parameters and 24 total runs. As far as i know "Resolution IV" means, that the Main Effects are not confounded with Two Factor Interaction, so they can be…
