We are going to delve into “User Expressions”. This is a topic that scares many an eQUEST user, so let me be clear, you can very easily complete an eQUEST model without “User Expressions”. They are optional, but they can be very helpful.
What is a User Expression in eQUEST?A User Expression, also called a User Input Expression, is an input that is dependent on another input. This is very powerful because it allows interdependence of inputs, and allows dynamic modeling. To really explain a user expression, let’s start out with a simple example.
Example 1:
Let’s say we wish to place one window on each wall in our simulation. It’s common that a band of glass...
