Dear 婧毓任,

As explained in another post: RE: python - plaxis 2d soil material parameter
the property that is required to be included is the FlowDataModel. By configuring this manually and using the echo command, you can identify that for USDA that should be set to 200.

Note that in our latest PLAXIS versions, this is no longer an issue as the definition of the materials is improved.

mc_params_gw = [("MaterialName", "Sand_MC"),
                ("SoilModel", 2),
                ("Gref", 25E3 / (2 * (1 + 0.3))),
                ("nu", 0.3),
                ("phi", 29),
                ("FlowDataModel", 200),  # specific integer for USDA
                ("DataSetFlow", "USDA"),  # USDA
                ("SoilTypeFlow", "Coarse")]
