TopOpt vs Dsod Erasmus
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TopOpt
Explore structural engineering concepts with an interactive topology optimization tool. Design and visualize optimized structures in real-time by placing loads and supports. Supports advanced features like volume and stress constraints for detailed analysis.
- Real-time structure updates
- Minimum compliance optimization
- Compliant mechanisms design
- Local volume and stress constraints
- Robust formulation for design insensitivity
- STL export for 3D printing
- Interactive load and support placement

TopOpt is an interactive topology optimization app from the TopOpt group at the Technical University of Denmark (DTU). Place loads and supports, and the optimized structure appears and updates in real time while you edit. Two problem types: • Minimum compliance: the stiffest structure for a given amount of material • Compliant mechanisms: a force inverter and a gripper, with input and output ports and their springs Both can be extended with: • A local volume constraint for bone-like porous infill • A von Mises stress constraint, with the stress field shown on the design • The robust formulation, which makes the design insensitive to its members being made thinner or thicker Further features: • Presets: MBB beam, L-bracket, cantilever and femur, and force inverter and gripper for mechanisms • Up to six loads and three load cases, and scaled loads • Loads, supports and ports are moved by dragging their symbols, and loads and ports can be rotated • Passive solid and void regions, and flexible void regions that the optimization may move • Custom grid size, sharpness and filter radius • Export of the design as an STL file for 3D printing The same app runs on iPhone, iPad, macOS, Windows and Linux. A user guide with tutorials is available on the TopOpt homepage.

Project DSOD- “DISADVANTAGED STUDENTS OVERCOMING THE DISASTERS” is a Project carried out in the concept of Erasmus+ Programme of EU Comission in the field of Ka2- Cooperation Partnerships. DSOD aims to create the key competences of individuals and Professional skills of educators to manage the safety of disabled people and students in case of any disasters or emergency situations. DSOD provides a Practical Guide for different scenarios, research and articles from different countries, an OER, Mobile App and Interative content to lead the safety of disabled people. DSOD has been implemented during 2021-2023 years by partnership consisting of organisaitons from Lithuania ( Coordinator ), Turkiye, Greece, Portugal and Romania.

Verdict
The clearest difference is device support: TopOpt at 3 against Dsod Erasmus's —. Dsod Erasmus's advantage is iOS requirement (13.0 vs 15.0). On price and in-app purchases there is nothing between them.
