blog details: Aerodynamics play a vital role in the designing process of vehicles. With CCM, the external flow around the upper body of the vehicle is analysed. The parameter used for this purpose is the drag force that affects the fuel economy. CCM plus is a software that is widely used for the purpose of aerodynamics analysis. Users often face confusion in choosing the right software for Computational Fluid Dynamics (CFD), because of the large variety of commercially available softwares in the marketplace. STARCCM plus estimates the solutions to complex problems like solving complicated partial differential equations that govern fluid mechanic problems, using numerical techniques. Aerodynamic drag consists of two major components- skin friction drag dependent on vehicle geometry due to the boundary layer separation from rear window surface and wake region that is formed behind the vehicle. This location of separation determines the value of aerodynamic drag.
The strategy of mesh optimisation is adopted for the purpose of estimating the drag of a ground vehicle on the basis of different mesh parameters. The Design of Elements (DOE) method is used that enables stimulations to be carried out in a timely manner and limited memory environment. There are parameters that lead the drag values closer to less computational time and less memory. Also optimised mesh size is scaled with the length of car model successfully used to predict the drag of the other car sizes with reasonable accuracy. This examination was carried out using STAR-CCM+, that uniquely brings automated design exploration and optimization to the CFD simulation toolkit. This environment includes everything ranging from CAD, automated meshing, multi physics CFD, sophisticated post processing, and design exploration. There exists comprehensive analytical models that include all aspects of design of electric machines that includes thermal, electromagnetic and drive control. Efficient utilisation and elimination of magnets are structured to give seamless design capability over the entire range of permanent-magnet machines.
With many options at bay it is important to choose the one that caters to all your needs and has more strengths than weaknesses. Choosing the right software for the main purpose is essential to realize elements of ideas without wasting time using the wrong tool. Fluidmech has one of the most robust suites of features and workflows that users can access in a single program, it is the best choice for a feat that increases efficiency, low cost of entry and approachable interface. Fluidmech has Siemens as its authorized partner, NX, Starccm+ and Solid edge that tackles 3D modeling. Fluidmech in a number of different ways like digital sculpting, mesh-based modelling, and parametric modelling. It is hard to convey just what sets Fluidmech apart.
