Turn field load tests into defensible model parameters.

Myers₃ orchestrates PLAXIS 2D calibration across measured settlement and strain response while preserving the evidence an engineer needs to review every result.

What Myers is

Myers is a Windows desktop application that drives your licensed PLAXIS 2D installation — calibration runs on your machine, in your PLAXIS environment.

01Import field evidenceSoil profiles, load stages, settlement, and strain response
02Run controlled trialsTransparent bounds, convergence status, and conservative weighting
03Review before useMeasured/modelled comparisons, validation gates, and trial lineage
One controlled workflow

From source data to an engineering decision.

01

Read the project workbook

Read your soil profile straight from an Excel workbook. Myers₃ derives effective stresses, splits layers, and builds the model parameters — no manual transcription.

02

Refuse bad inputs early

Validate geometry, target ordering, material consistency, and PLAXIS connectivity before a calibration trial starts.

03

Search parameter space

Myers₃ drives PLAXIS 2D under an optimizer, searching parameter space to reproduce the head deflection, settlement, and strain-gauge response measured in your pile and foundation load tests.

04

Apply the right soil model

Handles Mohr-Coulomb and Hardening Soil parameters, including small-strain stiffness (HSsmall), with effective-stress integration, layer splitting, and groundwater adjustments built in.

05

Interrogate the evidence

Each calibration reports a best-fit RMSE and clear pass/fail verdicts, so you can trust — and audit — the parameter set before it reaches your production model.

06

Keep complete trial lineage

Archive configurations, parameter states, convergence status, objective values, and outputs so accepted results remain traceable.

Evidence, not just an answer

A calibration result you can challenge.

Every reported fit stays connected to the field targets, material changes, convergence behavior, and configuration that produced it.
