I have been using a command like the following to get models into Wolfram language:

model=SystemModel["EducationExamples.Physics.GyroscopicPrecession.HelicopterModel"]

But now I need models that don't come in the standard package but are available for free in an external library. Since I don't have SystemModeler installed on the machine I can't use its GUI interface to install the library. So what is the Wolfram language way to install this library.

model=SystemModel["BioChem.Examples.MichaelisMenten"]

I have downloaded the file:

BioChem_1.3.1_MULT.sma

So where do I put it so Wolfram language detects it?

  • $\begingroup$ As an exmaple, the model "IntroductoryExamples.MultiDomain.DCMotor" can be found under: "...Math12.1\SystemFiles\Components\WSMCore\L\IntroductoryExamples\MultiDomain" as file "DCMotor.mo". Therefore I guess that your model should go somewhere close. $\endgroup$

  • $\begingroup$ @DanielHuber but the downloaded file is a library file with extension .sma not .mo so this might not work. $\endgroup$

  • $\begingroup$ Are you sure that this is a file for MMA? MMA help say<s that you need a file with extension ".mo". $\endgroup$

  • $\begingroup$ .sma is a file format created by WRI in order to have a "flat" model file that includes all model dependencies (→Documentation). Import of such a file will give a SystemModel. $\endgroup$

System modeler libararies are aparently imported like follows:

Import[FileNameJoin[{...path to file...,"BioChem_1.3.1_MULT.sma"}],"SMA"];

Now this works:

model=SystemModel["BioChem.Examples.MichaelisMenten"]

If there is a better and more official way to import the system modeler libraries in WL, feel free to edit.
