Computational fluid dynamics software (CFD) is used for the calculation of flow parameters in fluids, and for the design and simulation of the behavior of fluidic systems.
Engineering analysis and modeling software is designed to model, analyze, and predict responses and interactions for applications such as materials, structures, chemical and biological processes, electronic system performance, etc.
Engineering consulting firms provide engineering services and expertise to companies in need of a specialized skill-set. Professionals in this category work with clients to define solutions to problems or to help determine and recommend the best course of action for a given initiative.
