What's New in Deflection

11.0.0

March 19, 2025

Introducing frame and building benchmark examples and extensive improvements throughout the app! • NEW: Examples gallery in the home screen, including new examples for frames and buildings. Click on the button with a book icon to open it. • NEW: The new eyedropper button in the frame editor allows you to copy the material and cross-section from one beam to another. To use it, select a beam, press the eyedropper button, and then select another beam to copy from. • FIXED: Cross section stress analysis for angles and zees is now performed along their principal axes rather than geometric axes. • IMPROVED: Numerous performance, stability, layout, and interaction enhancements in the 2D editor, especially when working with large models. Thank you for your continued support and feedback! Reach us at contact@ketchep.com with any questions or comments.

How to change 3d to 2d

Idk

Pro 버전

가격을 쫌 낮춰주세요 ㅠㅠㅠㅠㅠ

Unausreichend

Keine in Deutschland üblichen Stahlprofile. Fließgelenke oder ähnliches lassen sich nicht einfügen... Ich habe mein Geld rausgeschmissen.

Buena App

Después de un problema por no interpretar bien mis datos, di con la solución. Ahora tengo dificultad con la edición de longitud en el módulo de cerchas 2D, que entiendo me resolverán

Matrices

Me podrían ayudar si la app también me ayuda con las matrices de rigidez, identidad y transpuesta, de las vigas?

FAQ

What kind of structural analysis does this app perform?

This app performs structural analysis for beams, 2D trusses, and 2D frames. It calculates reaction forces, shear, bending moment, and deflection. It also computes internal shear and bending stress along the cross-section and the beam.

Can I design custom cross-sections?

Yes, you can edit built-in cross-sections using the cross-section editor. The app automatically calculates moment of inertia and area values, which are then applied to the beam calculations.

Is this app free to use?

Based on the provided information, the app is a paid application. It does not have in-app purchases or advertisements, indicating a one-time purchase model.

What are the main benefits of using this app for structural analysis?

The app offers a simple and intuitive interface with state-of-the-art graphical output. It provides detailed results including internal stresses, and features a seamless 2D editor for frames and trusses, along with a built-in database and templates for convenience.
