Engineering notes should preserve not only results but also the process used to reach them. At minimum, record the purpose, input values, assumptions, tools, and results together.
Recommended structure
| Item | What to record |
|---|---|
| Purpose | The question being answered |
| Conditions | Materials, boundary conditions, and versions |
| Method | Equations or experimental procedures |
| Results | Tables, figures, and raw data locations |
The energy of a simple model can be written as follows.
Keeping code and figures as separate files makes later maintenance and CDN migration easier.
energy = 0.5 * stiffness * displacement**2
