computational fluid dynamics (cfd) has become an essential tool in modern engineering analysis and thermal management, leading to faster solutions and an increase in productivity. it is also a very rich field that has benefitted from decades of work to improve its accuracy and speed.

thus, today, engineers have at their disposal an array of different choices of cfd packages to solve theirthermal problems. it is beneficial, however, if the user possesses a basic understanding of the underlying concepts, so that he or she can utilize the cfd software more effectively.
