We offer a wide variety of services to help businesses of all stages achieve extraordinary results

NUMERICAL SIMULATIONS

Not every problem needs a high-end 3D analysis. We believe in proper and holistic approach to a problem, using our knowledge and experience in modeling, research, and mathematics capabilities.

When 3D analysis is the right answer, we propose the best tools at our disposal to perform numerical tests in order to efficiently deliver the results you need to move your project forward.

We have an expertise in simulation technology such as Computational Fluid Dynamics (CFD) analysis or Finite Element Analysis (FEA), and we will offer the solution to address your design challenges.

Using the latest CFD software, we excel at all types of Computational Fluid Dynamics simulations—no matter how complex or critical your project is.

Nivas holds unique capabilities in Computational Fluid Dynamics (CFD). 

CFD software analyzes fluid-flow and heat-transfer designs, allowing engineers to determine how a design will perform under real-world conditions and to highlight opportunities for optimization ahead of time, thereby reducing risks and avoiding costly warranty problems.

Our main areas of expertise:

  • Steady state and transient simulations of internal or external flows
  • Analysis, design and optimization of components
  • Optimal turbulence modeling approaches: RANS, URANS, RSM, LES, DES
  • Incompressible, compressible, subsonic, and transonic flows
  • Rotating equipment and moving bodies
  • Moving reference frames, rotating and sliding interfaces
  • Two-way fluid-structure interaction
  • Heat transfer and thermal modeling
  • Multiphase and free surface flows
  • Flow mixing

Nivas offers a complete range of finite element analysis (FEA) services for manufacturers that have rush jobs or lack the necessary FEA expertise and software in house to tackle complex challenges.

FEA is a computational method of optimizing structural design, which digitally analyzes materials or objects to determine the effects of real-world stresses such as vibration, heat, fluid flow, and other applied forces to identify points of weakness, allowing engineers to optimize overall performance goals without sacrificing size, cost, or aesthetics.

Nivas’ team have knowledge and experience in the fluid-structure interaction field, using different types of software tools. 

Fluid-structure interaction (FSI) is the multiphysics study of how fluids and structures interact. The fluid flow may exert pressure and/or thermal loads on the structure. These loads may cause structural deformation significant enough to change the fluid flow itself. Undesired effects in your product may increase as the level of the fluid-structure interaction increases. We have practical as well as scientific background in order have a deeper understanding of the phenomena occurring with your product to ensure safety, reliability and longevity.
