The world's first Apple‑native structural engineering app

MacCiv is a fast, intuitive finite‑element tool for analyzing 2D and 3D frames — beams, columns, supports and loads — right on your Mac, iPhone and iPad. Model a structure, solve it, and read the axial, shear, moment and torsion diagrams, reactions and deflections in seconds.

Features

• 3D frame solver with shear, moment, axial and torsion diagrams
• Concrete, steel and wood members
• Teaching mode — see results as formulas (e.g. qL²/8)
• Seismic centres of mass and stiffness
• Metric & imperial units, 9 languages
• Native on macOS, iPhone and iPad
