Analysis / CAE

REDinvent Technologies brings in vast experience in the field of Computer-Aided-Engineering (CAE) for providing high quality services to engineering community across product, process and service industry. We offer services in the areas of Finite-Element-Modeling (FEM), Finite-Element-Analysis (FEA), Computational-Fluid-Dynamics (CFD), Multi-Body-Dynamics (MBD) and Fatigue-Life-Prediction (FLP).

Our industry experience of 40+ man-years adds value to entire spectrum of simulation involving strength, rigidity, durability, crash-worthiness, interference, contact and gap analysis. Hands-on experience in using software for one, two and three-dimensional, linear and non-linear, static and dynamic for applications like noise/vibration, ride/handling, thermal/flow, etc enables us to serve a wide range of industries spanning from white goods to automotive/aerospace to civil/structural.

Our domain experience in value engineering through topology/topography optimization and design synthesis using Design-Of-Experiments (DOE) helps in virtual product development for discrete CAE projects as well as programs with complete product life cycle responsibility. We strive to provide our customers, the much needed confidence in the form of Quality, Reliability & Durability (QRD) robustness and cost-effective designs with adequate Factor-of-Safety.

Finite Element Analysis (FEA) is a numerical technique for solving complex engineering problems using methods of approximation. The accuracy of analysis is much dependent on the closeness of approximation provided by the analyst. Mathematical modeling, applying boundary conditions and choosing the right type of solution technique decides the quality of analysis.

The next important part in FEA is results interpretation. von-Mises stress is used as a failure criterion for elastic materials, whereas for brittle materials that might not work out. Also for pressure vessel design half the ultimate strength is taken as the criteria for failure.

Other issues like choosing the right element, the right mathematical model etc. requires sound knowledge of FEA theory. Coordinate system is yet another tricky part when it comes to FEA. Interpreting results in local coordinates or global coordinates has to be decided based on which parameter is being analysed.

We have the know-how to perform general analyses like Stress analysis, Vibration analysis (Modal/Harmonic), FSI (Fluid Structure Interaction) and Contact analysis.

Current engineering systems demand analysing the various effects on the system like flow, heat transfer and combined effect of different energy systems. Finite Element methods are advanced enough to cater to such industry needs. Flow and thermal analyses are now used in the design of blowers, heat sinks, data center cooling systems, and large HVAC systems.

Computational Fluid Dynamics (CFD) is used for more complicated flows involving mass and heat transfer. Examples are combustion modeling, turbine flow simulation, eddy flow simulation etc. CFD technique gives better results since it is based on Navier Stokes equation. This equation models any general three dimensional flow and hence can be used to model any arbitrary flow problem.
