```auto
m = MimiFUND.get_model()

```

I run this line and get  
Built: false

It seems to prevent me from going any further.

Thanks

Hi @charmeu thanks for posting! A `get_model` function will generally return an un-run model, which is not `Built` because it will be built at runtime. This model type holds a `ModelDefinition`, but no `ModelInstance`, since it has not yet been run, so certain functionality is not yet available until you run the model.

```auto
m = MimiFUND.get_model()

```

will obtain model `m`, and

```auto
run(m)

```

will run the model.

The `MimiFUND.get_model()` function returns a `Model` type (or struct), in this case variable `m`. What you type above is a summary of the structure, as replicated by `show(m)`, giving a little bit of information about it, which is expected.

You should be able to proceed with no problem, this is normal behavior. If you want to silence displays you may be able to use a `;` semicolon after your call, especially if you are in Jupyter Notebooks, but that is just an aesthetic choice.
