Fluid Library Concepts
The FlexSim Fluid Library consists of twelve objects. These objects are designed to aid in simul at a time, this value may be used to stop certain ports from sending or receiving. The maximum port rate is the maximum amount of material that will be allowed in or out any one port in a single time unit. This value applies to all of the input or output ports on the object. Each individual port is then assigned a scale factor. This scale factor is multiplied by the port rate to calculate the maximum rate for that specific port. These scale factors are used to restrict flow through one or more ports without affecting the maximum flow through the others. These three values are applied separately to the input and output ports. 
All of the fluid objects use this system to transfer material. However, because of the specialized nature of some of the objects, not all of these values may be available to the modeller for editing. Instead, some limited subset of the values will be presented and the object will maintain the other variables behind the scene. All of the values that the user can edit are presented in the GUI's for each object, and will be discussed in more detail later.
Each object also keeps track of a value called the Product ID. This is a number that is used to identify the type of material that the object is currently holding. The product may contain sub-components. This is a list of all of the possible sub-components in the
model. The list is recorded as a set of percentages of each sub-component. The Product ID number of an object does not represent any of the sub-components. It is simply a number that the modeller assigns to a specific material. The Product ID of the objects, as well as the sub-components percentages will always be maintained by the fluid objects. The user only has to specify initial values on the objects that create fluid.
Most of the fluid objects have a system for displaying the current content of the objects as
