Hello.. I am defining the hypoplastic parameters for Karlsruhe sand (found in a paper) using MIDAS GTS NX. In the software the a requesting (in addition of parameters) the number of internal state variables, and the number of integer indicator variables.
I know how to define 22 parameters, my issu is how to define the number of internal state variables and the number of integer indicator variables

    I do not know Midas but according next link the umats from soilmodels are not compatible

      Thank you Arie..
      I saw an old comment for you about definition of pore pressure as temperature.. may to know how to define the analogy between hydraulic and thermal conductivity ? What to define for specific heat..

    QT=(T1-T2)*A*ktemp/L*dt [J]
    ΔT=Q/VRCtemp

    Qw= ΔhxAxkw/L*dt = (P1-P2)/9810xAxkw/L*dt [m3]
    kw=m/s
    ΔP=Qw/VxEwbulk

    => ktemp=conductility=Kw/9810
    => Ctemp=specified heat= 1/Ewbulk/R

    Dear Arie..
    do you detailed document about this analogy?
    could you please explain more about units and the definition of each term you mentioned because i am confused little bit
    Thanks a lot
