Black elements

FrigoSim uses black colouring to indicate that a specific element is incompletely specified. This applies to both basis components and plant components. Basis components are normally grey-coloured. When one or more data elements are missing, the colour turns black. Plant components are normally coloured by the fluid that is contained within and/or is flowing through. If the corresponding basis component is black, or some initial condition is unspecified, the plant component is presented black.

Black colouring is also used to indicate that a given circuit is not properly specified. The connectors (if selected to be viewed) turn black.
