KATAI 2D
Version 0.2 is in active development and is not yet publicly released. The current work is on the constitutive model layer and on extending the verification suite — 89 checks pass on every build today, and the useful question is not how to raise that number but which capability is still resting on an untested assumption.
The scientific manual is published and citable at doi:10.5281/zenodo.20692282. Early access registration is open at kataigeo.com.
Writing
One substantial article roughly every three weeks, on soil mechanics and site data. Twelve good articles are worth more than sixty thin ones, so the cadence is deliberately slow.
Smaller tools
Ongoing work on automating the path from site investigation data to design parameters — starting with classification from a grading curve.
