Technical notes
How we work, in detail
Short notes on meshing, convergence and validation. Method, not marketing.
- Particle
An uncalibrated DEM model is an animation, not a calculation
Which bench tests constrain each contact parameter, the order they are fitted in, and why a calibration only holds inside the envelope it was tested on.
- Flow
The rainbow scale invents edges and hides gradients
Jet's non-monotonic lightness manufactures false bands and flattens the middle of the range. What viridis and cividis fix, and how we fix the scale.
- General
A run without a mesh study is not a result
What a mesh sensitivity study is, how we document it with GCI, and what y+ actually means when you decide where the first cell goes.
