Thus, in this chapter, we first give examples of the different types of information that are useful in various biomedical situations. Sometimes and especially for a newcomer to modeling, it may not be obvious as to which raw or derived information is most relevant in relating back to the physical problem. If this is all that is needed, one simply learns the respective commands from the software interface. Standard quantities to be displayed or standard computations to be made are built into a typical software. A simple post-processing step could be the display as a graph of the data produced by computations, for example, a plot of concentration calculated at a point as a function of time. Post processing is the further processing of the raw data produced by the computation. This stage is also called post-processing. This chapter simply presents ways of visualizing and manipulating the results of computation using a software, and its relation to other chapters is shown in Figure 4.1. Remember, computational results are not a solution to our problem until we have validated the results. Once a “solution” is available, we can visualize and analyze it to make sense of it. After these steps, the computer simply solves the equations- a step called processing that is completely automated. These steps together are called preprocessing as discussed earlier. In the previous two chapters, the mathematical model consisting of the governing equations and boundary conditions were implemented in a software, together with instructing the software how to solve the equations.
