EDA Offers Solutions to Complex Engineering Design and Analysis Problems
EDA Ltd. is an engineering design and analysis company providing services since 2003 for mechanical and aerospace engineering projects of various industries, such as aerospace, automotive, energy, power and consumer products. The company is located at the Middle East Technical University campus in Ankara Turkey. EDA constantly seeks innovative, cost and time effective solutions for difficult engineering problems of industry. It offers solutions to complex engineering design and analysis problems with its highly competent technical staff. EDA’s team of engineers hase a total of over 45 years of experience, with experts from mechanical, aerospace, chemical, computer, engineering mostly with PhDs.
What are EDA’s research & development activities?
EDA closely follows technological developments and discoveries worldwide to address the future demands of its customers and to upgrade its service quality and work efficiency. Its research and development concentrates mainly on evolution of its design and multi-physics solution capabilities. EDA’s research activities, in which scientists from national or US universities have taken part, have been partially funded by the Scientific and Technological Research Council of Turkey (TUBITAK). Additional support is provided by the Small and Medium Enterprises Development Organization of Turkey (KOSGEB).
What type of engineering software EDA uses?
EDA uses only its own software CAEeda™ for engineering design and analysis developed during the course of last ten years. CAEeda™ has following modules from solid modeling to design optimization all integrated. This way, it does not depend on any third party software. By using Linux operating system, it is also independent of any kind of proprietary operating system, under fully secure environment. Presently CAEeda™ has the following modules:
Geometry module (CADeda)
Interactive multiphysics module
Mesh generation module (MESHeda)
Optimization module (TOPeda)
Flow analysis module (FAPeda)
Pre-processing module (PREeda)
Structural analysis module (SAPeda)
Post-processing module (POSTeda)
Thermal analysis module (TAPeda)
6 DOF module
Ballistics module (BALLISTICeda)
What are some of the capabilities of EDA?
EDA’s engineers continuously seek for cost and time effective solutions for design projects and utilize all levels of computational tools ranging from basic engineering methods to advanced high fidelity solvers depending on design requirements. With its highly parallelized software, EDA can provide solutions to large-scale engineering problems only in hours instead of days and months. EDA has design and analysis capabilities for airframes of missiles, projectiles, aircrafts, helicopters, unmanned air vehicles, submarines, torpedoes and thermal cooling and heating systems. For multidisciplinary problems such as aero-elasticity, aero-heating and store separation code/mesh coupling methods are used in CAEeda™, including aerodynamic 6 DOF coupling.
Why CAEeda?
CAEeda™ provides highly sophisticated design-based analysis tools in the hands of engineers. Most engineering problems require: 1) geometric/solid modeling of parts or products to be designed, 2) generation of computational meshes for analysis, 3) computations for performance under external effects, 4) visualization of results, 5) optimization for better performance. An integrated solution for all these steps of part or product design is provided with CAEeda™. During the feasibility stage for technical and affordability features of a product during the conceptual phase, there is a need for practical and fast simulation tools. Selection of different levels of modeling is offered by CAEeda™. The fact that EDA does not rely on third-party software for any of its products provides the fast response to solution of problems the vendors of most commercial codes can’t. Its friendly user-interface, including for parallel computing across multiple processors, reduces human labor.
Capabilities range from simplified engineering tools for conceptual phase of a design to more advanced tools such as topology and shape optimizations in the final stage all in one package, CAEeda™. As an example of a simplified tool shown in Figure-1 is a parametric airframe design of an Unmanned Aerial Vehicle (UAV). Shown in Figure-2 is flight simulation of the same UAV after quick computing of aerodynamic loads based on semi-empirical component build up method. Figure-3 illustrates results of an advanced simulation, where structural topology of an UAV wing under aerodynamic loads is obtained. While the first example can be solved in seconds, the second problem requires more computing time and resources, even with CAEeda’s parallel features on hundreds of computer processors for CFD and topology optimization.
