Critical Elements of Pre-ProcessingĪs mentioned above, CFD analysis is only as good as its implementer - that is, how accurate can the designer set up (or pre-process) the model - as the initial design will eventually affect the model in the later phases of analysis. In this step, you will need to identify the domain of interest and divide it into several small segments – this includes preparing the geometry, meshing it, defining the properties of the materials involved, and setting the boundary layer and conditions. Pre-processing is the first step in CFD simulation - which can help to define the parameters of the simulation in an accurate way, if done properly. In addition, surgeons can cure arterial diseases through computation hemodynamics, while meteorologists can forecast the weather more accurately and warn us of impending natural disasters.ĬFD analysis consists of three main steps: pre-processing, processing and post-processing - here is a brief introduction to each of them. With CFD software solutions architects can design safe and more comfortable living environments while vehicle designers can improve the aerodynamics of the vehicles they produce. While this form of analysis still requires ongoing improvements, technologies (and the individuals who run it) are getting better everyday. Computational Fluid Dynamics (CFD) is a type of analysis that provides insight into solving complex problems, and allows engineers the ability to test the effects of fluid flow on their designs - this is done without the need to conduct real-world experiments.ĬFD can help simulate aerodynamics, thermal heat transfer, and turbulent flow on 3D models by automating mathematical principles like Partial Differential Equations (PDE) and navier stokes.ĬFD analysis has proven more helpful in day-to-day, real world applications especially given the wide range of use case across various industries - including architecture, vehicle design, petroleum engineering, surgery and meteorology.
