    Professor Masin,

    Thanks for sharing the code.

    I have a question concerning how to specify stress path, for instance compression drained, say for “hypo_sand” model?

    I found in update.m there is a matrix named “path_info”, but cannot find further information on this.

    Thank you for your time.

      Hi Xiang, this is defined in input_data.m, using “icode” variable. Explanation of codes is in comments. drained triaxial compression has icode=4. David

    Dear Prof.Mašín,
    Thanks for your explanations and directions in this forum.
    I solicit you to send me the hypo version for unsaturated soils for Plaxis.
    Thank you for your time.

    Hi Professor Masin,
    I am trying to code the ISA and ISI hypoplastic model in Matlab but couldn’t succeed yet(ISA cyclic hypoplasticity Fuentes, W., et al., ISA-Hypoplasticity accounting for cyclic mobility effects for liquefaction analysis. Acta Geotechnica, 2020. 15(6): p. 1513-1531. and ISI Duque, J., D. Mašín and W. Fuentes, Improvement to the intergranular strain model for larger numbers of repetitive cycles. Acta Geotechnica, 2020. 15(12): p. 3593-3604. ). Could you provide a Matlab code to help me with my reserach? Thank you for your time.
