The way to do it is exactly the same as for the inputs, with the only difference now being that you press the red button instead of the green one. The red circle button is used to add outputs to the model. You can drag and drop these input and output places and the transitions anytime you wish to change their positions in the model. You can also drag and drop the names. Play around until it looks nice. Now, our model boasts of three places and one process.

What else does a material flow model need? Flows, of course! To connect the symbols with each other, we create three flows. One from each input to the process, and one from the process to the output. Select the following button from the model toolbar:. Drag the arrow to the blue process symbol. Hovering there will make that symbol turn gray, too. Now release the mouse. We clearly need two more arrows, one from the second input to the process and another from the process to the output.

Well done. If you move the symbols around, you will see that the arrows automatically adjust. Just select the arrow, delete it, and draw a new one, this time paying a little more attention to the symbols turning gray.

So far, our model consists of two inputs that lead to a process that, in turn, leads to an output. By now it should look something like this:. Next up, we feed our model more information on the necessary materials to produce PE. Still, to suit the needs of this tutorial, the following rough simplification makes sense. There are two ways to get these materials into our model.

That database is called ecoinvent 3. You can browse through it in the project explorer top left corner.

To find a material or an activity in the database, type your search term, e. However, the results for natural gas materials in the exchanges menu are countless.

We can add as many materials as we want. We can also add energy, which, for reasons known only to programmers, is also treated as a material in Umberto. Look at the project materials folder at the top left, in the project explorer. Found it? Now that you have all necessary input materials, you can start to think about how to specify the process calculation. The left column lists all relevant inputs, the right one the outputs. But this is much more than a list.

Just drag and drop each material from the project explorer window into the input column, as shown here. Note that the process has to be selected for the specification window to work:.

The right column is for the outputs. And as before, we drag the material from the project explorer and drop it in the specification window, only this time, we put it in the output list, the right column. The window that opens gives you free choice to manually add materials at the top of the list, followed by all options from the ecoinvent database. Umberto Case Studies overview.
