This is a really interesting offshore engineering project! For actual simulation software, you'd want to look at: **Industry-Standard Options:** - **OrcaFlex** - The gold standard for offshore structures, cable dynamics, and mooring analysis - **ANSYS AQWA** - Full hydrodynamic analysis for semi-submersibles - **WAMIT** - Panel method for wave interaction analysis - **MOSES** - Vessel motions and mooring design - **OpenFAST** (free) - NREL's offshore wind tool, adaptable for floating structures Below is an interactive 3D visualization and basic simulation of your seastead concept. It includes wave response motion, force visualization, and adjustable parameters. This won't replace proper FEA/hydrodynamic software, but it's great for concept visualization and understanding the mechanics. ```html Seastead Platform Simulator
