DOME provides live feedback on status of computations. Live feedback can be particularly useful for a simulation that takes a long time to finish and involves a large number of parameters and models, which is often a case in a design associated with renewable energy technologies. During a computation, users can observe the status of a parameter's value from the color coding surrounding the number.
Green means that the value of the parameter is up-to-date, but may need to be rolled back if any subsequent computations fail. Yellow signifies that the value of the parameter is changed by the user as an input. The color turns into green once the user presses the submit button. Red means that the value of the parameter is incoherent with the inputs and will be updated later in the computation. Lastly, White means that the value is final. With the feedback mechanism, users of the Alternative Energy Design Toolkit can determine which values are reliable in real time, resulting in more transparent and comprehendible design process.
