!! Solutions
The BMI is calculated using DiaFlux models, where first the "Height" and "Weight" is asked to the user.
Then, the value of the abstraction "bmi" is derived, when values for the aforementioned questions are known.
Final solutions are derived depending on the result of the calculated value of "bmi".

Here we follow with some basic stuff that is needed to tell the system, that we have a knowledge base here. Using the menu that expands when hovering over the small book icon on the right, you can also export the knowledge base as a .d3web-file to load and run it in your own application (click ''Download''), or start a one-choice-dialog for this demo (click ''Run Interview'').
