Simulation of printing processes involves modeling of complex processes and
materials. It has to be accurate and provide results in a timely fashion.
Detailed modeling of printer components and the target of modeling entire
printing process are discussed. Technalysis modeling activities towards this
goal is summarized. Several case studies are presented describing approaches
taken. Development of continuum, particle models, their coupling and
analysis of the overall system are emphasized. Close cooperation between
test and simulation is
referenced both for determining material properties and for validating
simulation models. Testing and simulation have to be used concurrently to
reduce time to design and improve quality. Recent activities have been
centered around strong coupling of particle and flow problems.

Although simulation techniques have been investigated for several years by
researchers, implementation of these techniques to design of printers still
remains to be improved. Design of a printer requires intimate knowledge of
the details as well as overall understanding of the system performance.
Design process relying on testing can be tedious and time consuming.
Simulation can provide insight to difficult problems which cannot be
measured in detail and may provide faster answers. Yet, we are still far
away from providing a complete simulation model for a printer. For
developing models of printing
processes, two major issues appear : accurate representation of
material modeling and the efficiency of computational effort
required to obtain desired accuracy. Material is complex and
many different physics problems need to be solved. A brute
force approach to compute some of these problems is not
practical with existing supercomputers. Besides developing these methods,
developing strategies to implement them into design process also requires
considerable effort. From the designer's point of view, again there are two
main concerns : accuracy and time required to get meaningful results. We
comment on the information which can be obtained from these models.
In this paper, we review some of Technalysis development
activities and efforts in providing simulation tools which can be
used by the designers. We give several examples addressing
solution of different problems where simulation can be utilized....
