Dynamics refer to the branch of mechanics concerned with the forces that cause motions of bodies. Commonly, dynamics is associated with the study of anything that flows or moves, as in water flowing in a pipeline or air moving in a room.


  • Computational Fluid Dynamics (CFD)

    Computational Fluid Dynamics (CFD)

    A CFD software is an advanced technology which enables the study of the dynamics of things that flow. Using CFD, a simulation model that represents a system or device in design stage is built. By applying the theory of fluid flow physics and chemistry to this virtual prototype, the software will generate a prediction of the fluid dynamics and related physical phenomena. Through the analysis of the results generated from the incorporation of the design and its details into the simulation model, one is able to determine the flows of gases and liquids, heat and mass transfer, moving bodies, multiphase physics, chemical reaction, fluid-structure interaction and acoustics. Through CFD , one will be able to gain a deeper understanding of the design, its performance and its resilence to what-ifs situation. Consequently, proper refinement can be exercised to ensure that the design is virtually “perfect” prior to materialization.
  • Finite Element Analysis (FEA)

    Finite Element Analysis (FEA)

    The finite element method (FEM) or finite element analysis (FEA) refers to a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The Finite Element Analysis is a good choice for solving partial differential equations over complicated domains (like cars and oil pipelines), when the domain changes (as during a solid state reaction with a moving boundary), when the desired precision varies over the entire domain, or when the solution lacks smoothness. FEA allows detailed visualization where structures bend or twist, and indicates the distribution of stresses and displacements. The FEA software provides a wide range of simulation options to faciliate the modelling and analysis of a system. Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications. FEA allows designs to be constructed, refined, and optimized before the design is manufactured.
  • Pipe Stress Analysis

    Pipe Stress Analysis

    Process and power piping are usually checked to verify that the routing, nozzle loads, hangers, and supports are strategically placed and selected such that allowable pipe stress is not exceeded under various situation such as sustain, operating, hydro test etc as per the ASME or any other legislative code and local government standards. Pipe Stress analysis is a term applied to calculations, which addresses the static and dynamic loading resulting from the effects of gravity, temperature changes, internal and external pressures, changes in fluid flow rate and seismic activity. Codes and standards establish the minimum requirements of stress analysis. Purpose of piping stress analysis is to ensure the safety of piping and their components, the connecting equipment and supporting structure and that limits of pipe deflection are not exceeded. This form of analysis is especially crucial in areas where there are occurence of earthquakes, high wind, vibrations or water hammer.
