Where does the element stiffness matrix actually come from? A full derivation from virtual work, through shape functions, to the 12×12 frame element matrix you use every day.
I built an MCP server on top of ETABSSharp that lets AI assistants query, modify, and run analysis on ETABS models through plain English. Here's how it works.
ETABSharp made ETABS automation testable and composable. Saola takes that one step further — bringing it into Grasshopper so structural engineers can build parametric ETABS workflows without leaving the canvas.
The raw ETABS API is verbose and weakly typed. Here's how I designed a fluent C# wrapper that makes structural automation actually enjoyable to write and get help from LLM.
