For PLAXIS 2D or 3D CONNECT edition V22, in order to define a soil/rock material with a specific soil model directly via the command line or via remote scripting, you can use e.g.

to add a new material:

soilmat "Identification" "Sand" "SoilModel" 2 "ERef" 2500

or using the Soil Model name as a string:

soilmat "Identification" "Sand" "SoilModel" "Mohr-Coulomb" "ERef" 2500

You can change the material model:
```
set Sand.SoilModel "Hardening Soil"
```
Or alternatively:
```
set Sand.SoilModel 3
```
To edit multiple properties at the same time you can use the following command:
```
setproperties Sand "SoilModel" "Hardening Soil" "EURRef" 3000
```

As can be seen in the commands above, the name of the soil model (e.g. Mohr-Coulomb) can be represented by a number or string. In the table below you can see the currently available soil models, their ID number to be used in the command line/remote scripting and the minimum defined parameters that are needed for a correct soil model definition that is accepted by the PLAXIS Input program.

For more information on how to define or edit a material via the command line, refer to the article How to define and edit a material via the command line.
