GeoEQ Cap tester version is available — looking for engineers to test before the free public release

[riponcm]

GeoEQ Cap is a Windows desktop application for the bearing capacity of shallow foundations by finite element limit analysis. Instead of a textbook formula with correction factors, it solves the problem you draw — footing, soil layers, water table, loads — and returns a lower bound and an upper bound on the collapse load, both independently checked after every solve.

A tester build is now ready, and we are looking for practising geotechnical engineers to try it before the public release.

What the tester build includes

• Strip and circular footings; any number of drained / undrained Mohr–Coulomb layers; water table, surcharge, placed surface loads, embedment; inclined and eccentric loads; pseudo-static seismic
• • Adaptive mesh refinement to a chosen bound gap
• • V–H and V–M failure envelopes, strength-reduction factor of safety
• • Result contours (collapse mechanism, failure band, stresses, strength mobilisation)
• • Independent comparison with Terzaghi, Meyerhof, Brinch Hansen, Vesić, Eurocode 7, AASHTO, IS 6403, BNBC, AIJ and a method-of-characteristics solution
• • Eurocode 7 / LRFD / ASD design formats, stated on the report
• • A calculation report as PDF, with every verification check listed against its limit
• • A 28-page user guide
    Reports from the tester build carry a TESTER VERSION watermark; the public release will be free (version 1.x).

What helps most

1. A case where the number surprised you — attach the .gec project file and say what you expected.
2. 2. Anything unclear in the interface or the report.
3. 3. What is missing for the work you actually do.
      Thank you for helping us get this right before it goes public.
