Reduce the Fan Noise of a Turbofan Aeroengine with Simulation

September 26, 2016

Noisy turbofan engines are often used to power commercial airplanes. You can reduce their noise pollution with the help of acoustics modeling…

Rotordynamics Fosters the Design of Reliable Rotating Machines

September 8, 2016

Rotating machinery is an important element in many structures. The analysis of rotating machinery, rotordynamics, can help engineers reduce noise and vibrations in many areas of technology.

Benchmark Shows Valid Results for a Piezoelectric Transducer Design

September 7, 2016

We walk you through the Composite Piezoelectric Transducer tutorial model: a benchmark model for ultrasonic transducer simulation and good starting point for simulations of SAW and BAW filters.

Using Simulation to Ensure the Cooling Efficiency of Refrigerated Trucks

September 6, 2016

To transport food, vaccines, and other perishables, refrigerated trucks are designed to maintain a cold temperature. Using simulation, researchers analyzed the cooling efficiency of such trucks.

How to Reuse a Deformed Shape as a Geometry Input

September 1, 2016

Let’s say you deform a shape in your model (say, by applying a mechanical load to a thin piece of metal) and want to use this deformed object as part of a new geometry construction. How?
