Before you start
New to Unity? The basic terms (Scene, Hierarchy, Project window, Play mode) are explained in Before you start.
What you need
- A lesson scene with a room and a player setup, made with Scene Generation.
- For measured or simulated data: the files from the lab or from the simulation. They stay on your computer (see below).
- For the AR digital twin: printed QR codes on the testing machine, set up with Positioning Setup.
Three kinds of bending lab
| Kind | Where the numbers come from | Good for |
|---|---|---|
| Calculated | The lab calculates the bending from the load, the dimensions and the material. | Exploring: "what if the beam were thicker, or made of aluminium?" |
| Measured | Force and travel recorded by a real testing machine, imported from a CSV file. | Comparing with a real test, for example one the class watched. |
| Simulated | Results from a finite element program, such as ANSYS. | Showing stresses inside the specimen, including around holes. |
What learners see and can do
- The specimen on its supports, enlarged so it's easy to see. The readouts always use the real dimensions.
- Stress colours on the specimen, with a legend. Learners switch between different stress fields.
- Shape - and Shape + exaggerate the bending to make it visible. This doesn't change any values.
- A cut-away or a section to look inside, where the data allows it.
- Graphs, for example force against deflection.
- With recorded data: Play / pause, Previous state and Next state to step through the test.
- With XR inspection switched on: grab the specimen with both hands to turn it and make it bigger.

Imported data stays on your computer
Imported lab and simulation data is saved in Assets/ALF/LocalSimulationData. That folder isn't uploaded to Git. Before you put imported data into an app for students, check that you're allowed to share it.
