Title

ExCalibre – SoilModels Automatic Calibration

Description

ExCalibre is an online tool which enables users to automatically calibrate advanced soil constitutive models. It adopts a unique model-specific calibration algorithm respecting physical meaning of material parameters, rather than using a blind parameter optimisation. It thus reproduces thinking of an experienced engineer calibrating the model, leading to a reliable parameter set to be used in geotechnical simulations. After calibration, the user can manually change the parameters to fine-tune the calibration or to investigate the effect of individual parameters on model predictions. Simple Excel spreadsheet based on the provided template is used as an input. In addition to automatic calibartion, ExCalibre also acts as an element test driver simulating standard laboratory tests.

      Hi Xianwei, yes, please wait few days or early weeks. ExCalibre is already fully functional, but we tune some final issues to ensure maximum robustness before we release it to public…

    Dear prof David Mašín thank you very much for sharing this useful software. Could you also provide the software manual and the theoretical guide?

      Dear Fracisco,
      Thank you for your interest.
      We do not have any dedicated “software manual” or “theoretical guide”.
      As a theretical guide, please study references from our pdf database related to the two constitutive models:
      https://soilmodels.com/hypoclay/
      https://soilmodels.com/hyposand/
      Actually , when you know what is going on, actually no software manual is needed. The software is programmed to be simple to use, the help text appearing when hoovering mouse above “?” should be sufficient to run it.
      Regards David
