- Geotechnical engineers using NorSand and CPT calibration
- Worth noticing
- Its model notes trace the JavaScript solver to a VBA module, itself described as a port of a MATLAB batch tool.
Field notes
The sensitivity workflow lets users vary one parameter over a range or list while holding the other inputs at base values. Multi-case input accepts p0_kPa, psi0, Ir0, and an optional k value; the notes say header lines are ignored. The model notes distinguish spherical symmetry, where K0 must equal 1, from cylindrical plane strain, where K0 may be any positive value.
