A small desktop program for solving 2D trusses, both determinate and indeterminate, by the displacement (finite element) method. You enter nodes, bars, supports and loads and get member forces, reactions and displacements, with unit conversion, influence lines and a PDF report. The latest release dates from 2023; the program is stable and best suited to study and quick checks.
