What is Modelling?

What is Modelling?

Build a Model before you build your real product!

You have an idea for a new product

Traditional Approach!

Build a prototype and test how it works. If it does not match up to your target performance, go back and re-tune the design. After multiple iterations, you arrive at the most optimal design for your product.

Building prototypes for multiple iterations is expensive. $$$

Modelling Approach!

Build a virtual protype, evaluate its performance by modelling and iterate though multiple designs until your virtual product meets the specifications. Since building virtual prototype is much cheaper, you can build multiple prototypes in the same iteration and arrive at the right design at a fraction of the cost of making real prototypes. Once the virtual design is satisfactory, go ahead and build your actual product in just one or two iterations.

Modelling at different stages of product development

  • Decks and Patios icon

    Initial Concept Phase

    During the initial concept phase of the product development, detailed finite element modelling is done to explore different design options by varying the geometrical shapes and dimensions.

  • Outdoor Spaces icon

    Detailed explorations of select designs

    One or two potential choices of designs are explored further in detail by varying the dimensions and the choice of materials used.

  • Custom Additions icon

    Build and test

    Once some prototype designs are built and testing begins, the modelling and testing results are compared. The model parameters may need to be fine-tuned at this stage, to match the modelling and testing results. Conversely, modelling is also helpful in understanding the test results and enable further innovation.

    Manufacturing and Sensitivity Analysis

    Once the design is finalized and the manufacturing begins, the effect of manufacturing variations on the product performance is done by a sensitivity analysis. Reduced Order Modelling / Lumped Element Modeling is very useful at this stage.

What is Multiphysics Modelling?

Many modern gadgets involve multiple aspects of physics in their operation. This is best illustrated, schematically, by the operation of a piezoelectric inkjet print head. The piezoelectric effect, which converts an electrical signal into a mechanical displacement is the fundamental actuation principle. The displacement produced by the piezoelectric effect itself is quite small. This needs to be amplified by a clever structural design that couples to the piezoelectric material. The actuator mechanism pushes a fluid (ink) and this in turn causes acoustic waves to propagate through the fluid. Eventually, the fluid pressure pushes out a drop of fluid through a nozzle. The different aspects of physics and the interactions between them are illustrated in the figure shown below. All these aspects are carefully modelled in our Finite Element Analysis for an accurate prediction of the product performance before it is built.
