A closer look
Every detail, in view
Included in version 1.0
From statics to finite elements, on your iPad
Validated against the books
Every result, checked against the textbook.
Each capability of Noctis Effect is tested against worked examples and problems from engineering textbooks: Hibbeler, Beer & Johnston, Logan, Singer & Pytel and more. Over 500 problems and nearly 3,000 values are checked automatically every time the app is built.
How it works
From a sketch to a solved structure
- Draw members with Apple Pencil or a finger; nodes snap and every length stays editable.
- Touch a node or a member to add supports, forces, couples and distributed loads from its fan of actions.
- Read reactions, axial forces, shear and moment diagrams and deflections, updated with every change.
- Learn with ten tutorials that end by comparing your result with the book.
- Export an illustrated PDF report, or share the study as a .noef file.
