RE: Setting DefaultValuesAdvanced using Plaxis Python API

Hi Rebecca,

With the command above, the K0NC value gets set to 1.0. As in PLAXIS V21 and earlier, the DefaultValuesAdvanced is an implicit value (i.e. the value will show as checked when vu_ur = 0.2, p_ref = 100 and K0NC = 1 - sin(phi)).

So adding the K0NC value to the command will work:

soilmat ("Colour" 11854222) ("SoilModel" 4) ("DrainageType" 0) ("gammaUnsat" 21) ("gammaSat" 21) ("K0Determination" "Manual") ("DefaultValuesAdvanced" True) ("perm_primary_horizontal_axis" 0.000864) ("perm_vertical_axis" 0.0001728) ("cref" 100) ("phi" 20) ("psi" 0) ("E50ref" 110000) ("EoedRef" 110000) ("EurRef" 300000) ("powerm" 0) ("gamma07" 0.00015) ("G0ref" 250000) ("K0NC" 0.65797985667) ("MaterialName" "Char_mdst_30_40")

Note that you also set the initial stress coëfficient K0 to manual, but you do not set a value. This means that they will remain 1 as well.

Note that with PLAXIS V22, we made these settings and default checkmarks explicit settings, so there it will work. Please be aware that some property names have changed in the new version.
