Whether it be finite element analysis or computational fluid dynamics, simulation technologies are crucial to designing to the highest degree. Our capabilities have come quite a long way in even just the last decade. The exponential rise of computers and the shrinking of transistors has meant that more complex simulations are becoming possible day by day. Simulation even now extends beyond just testing your design, programs are now capable of generatively designing a part based on constraints – a direct result of precise simulation.
Today’s architects and engineers can now analyze building performance early in the design stage thanks to 3D building performance simulation and finite element analysis.
Simulation tools allow them to effectively predict building energy performance, sustainability, and green features such as daylighting, as well as performance attributes such as airflow for heating and cooling needs, including computational fluid dynamics for buildings (such as data centers that require constant cooling). Thanks to the complexity of today’s building projects, simulation is becoming de rigueur for government clients and even private owners whose buildings must perform as advertised. AEC firms are being required to provide simulation proof that the design will work and that the energy consumption meets certain requirements.
So why do so many engineers choose not to use simulation when designing products? It has long been thought to be too expensive, too difficult to use, or that products are too mature for redesign. (Nothing is too old to be redesigned.) It’s also sometimes seen as a tool that is used only for predicting failure—but it can be so much more. It’s time to dispel these myths.

Early product design decisions by engineers are often done in a vacuum of information. Starting with an initial concept and testing as you go is a great way to collect data about what’s working and what isn’t that will ultimately get you to a better outcome. Learn four ways every engineer should use simulation during design to test ideas and make informed decisions.You don’t have to wait until the final stages of the design process to perform simulations. Here are four types of simulations all engineers can use to inform designs from the earliest stages until a physical product is created.
As consultants who specialize in simulation, we continue to expand our physical testing capabilities. For example, the image below depicts the results from both testing and CFD on a Raspberry Pi unit, which are very compact Linux machines we use for data acquisition and other tasks.
Sim Specialists recently traveled to Mexico City to deliver onsite FEA and CFD simulation services. The trip reminded me of a documentary I watched a few months ago about El Castillo, a Mayan structure located in the Yucatan peninsula region of Mexico.
The classic venturi tube, first designed by Clemens Herschel in 1887, has many useful applications in monitoring or controlling fluid flow.
CFD simulations of flow and thermal fields surrounding a smoke source, provide a visualization of smoke egress that can be leveraged to guide the design of smoke control systems required to meet smoke and safety regulations.
As users of Autodesk Simulation CFD and Autodesk Simulation Mechanical on a daily basis, we run into certain tasks that are repetitive or time-consuming. For many of these situations, it can be beneficial to develop a script to increase proficiency.
