Define Variables

There are two variables (A & B) to add to all four compartments. We will make use of the “Add To All Compartments” option to quickly add the same species to all compartments.

Steps:

  1. Select the “Add To All Compartments” checkbox.

  2. Press the “+” button to generate a popup.

  3. In Popup type “A B” separated by a space. Check “Numerical” instead of “Compartment Name” and press the add button. This will add the variables A_1, A_2, A_3, A_4, B_1, B_2, B_3, and B_4 to the model.
