Frequently Asked Questions

Numerical simulation is a digital method employed to predict the behavior of products or processes under tightly controlled conditions using mathematical models and calculations. It enables engineers to virtually test and refine designs before physical prototypes are produced.

CAE, or Computer-Aided Engineering, encompasses the utilization of computer software to assist in engineering analysis tasks, including simulation, visualization, and the analysis of engineering problems.

Numerical simulation aids in reducing the time and expenses associated with product development by enabling engineers to digitally test and refine designs, ensuring the product's performance meets expectations under different conditions even before building the first physical prototype.

Numerical simulations allow companies to avoid the high costs and time associated with multiple physical prototypes. They enable early identification of potential issues and design improvements, thereby reducing the need for expensive modifications later in the development process.

CFD (Computational Fluid Dynamics) is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems involving fluid flows. It enables engineers to simulate the interaction of liquids and gases with surfaces, predicting flow patterns, heat transfer, and pressure distributions without building physical prototypes.

FEA (Finite Element Analysis) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, and other physical effects. It breaks down complex geometries into smaller, simpler parts (finite elements) and uses mathematical equations to predict the behavior of each element and the whole structure.

We serve a wide range of industries including automotive, aerospace, energy (including renewable energy), maritime, electronics, HVAC, and manufacturing. Our simulation expertise can be applied to virtually any engineering challenge involving fluid flow, heat transfer, or structural analysis.

Tensor has been providing CAE (Computer-Aided Engineering) software and services for 26 years. During this time, we have built extensive expertise in numerical simulation and served clients in 5 countries worldwide.

Our process consists of seven key steps:

1. Discovery Meeting - Understanding your project requirements and goals
2. Numerical Simulation Setup - Creating the simulated digital environment
3. Preprocessing - Mesh preparation and boundary condition setup
4. Simulation Execution - Running the simulation with progress monitoring
5. Post Processing - Extracting and analyzing numerical results
6. Iterative Optimization - Repeating as needed for design optimization
7. Recommendations - Providing actionable guidance for improvements

To start a simulation project, we typically need:

• CAD geometry files (STEP, IGES, Parasolid, or native CAD formats)
• Operating conditions (temperatures, pressures, flow rates, etc.)
• Material properties or specifications
• Design requirements and acceptance criteria
• Any relevant test data for validation (if available)

Project duration varies depending on complexity. Simple analyses might take a few days, while complex multi-physics simulations could take several weeks. During our discovery meeting, we'll provide a realistic timeline based on your specific requirements.

We use ANSYS (CFD and Mechanical) for our consultancy and training services. We are also Value Added Resellers (VAR) for Cadence CFD products, and distributors of Particleworks, Frenetic, and ISS (Innovative Systems Software) products. The choice of software depends on the specific requirements of each project to ensure the most accurate and efficient results.

ANSYS software is a comprehensive tool utilized for various engineering analyses, such as structural analysis (FEA), fluid dynamics (CFD), and electromagnetic studies. ANSYS is used by engineers for validating designs and optimizing solutions before physical testing.

ParticleWorks is an advanced CFD software based on the MPS (Moving Particles) method. It is used to analyze the movement and interaction of fluids and solid particles, making it suitable for applications involving fluid flow, heat transfer, and related phenomena.

Frenetic Software is a specialized tool for simulating, designing, and manufacturing magnetic components like transformers and inductors. It leverages AI algorithms to optimize designs and enhance the efficiency of these components.

When properly set up with accurate boundary conditions and validated models, CFD and FEA simulations can achieve accuracy within 5-10% of physical test results for many applications. We follow industry best practices for mesh refinement, solver selection, and validation to ensure reliable results.

Yes, we can correlate our simulation results with your physical test data to validate the models. If you have existing test data, we can use it to calibrate and validate our simulations. This correlation process helps ensure the simulation accurately represents real-world behavior.
