How Can You Get More From An Oil Pump?

Imagine you have an oil pump in your car that has its outlet blocked. The pump is trying to throw the oil out but since the outlet is blocked the pressure in the pump keeps increasing. The excessive pressure that develops in the pump can be catastrophic to its strength and therefore life. This is precisely what happens when you try to operate the pump under extreme cold conditions, when the viscosity of the lubricant increases so much that the pump almost behaves as if its outlet has been blocked.

pumpsThis is a very common design scenario for pump manufacturers. Estimation of what is called as “shut-off” pressure and its implications on the structural integrity of the pump are key concepts that every pump manufacturer should bear in mind while designing pumps. Interestingly, simulations today allow manufacturers to develop deep understanding of such phenomenon and help them to design pumps, that perhaps they could not have, with just physical testing and prototyping.

Educating the Next Generation of Engineers

This is an exciting time at universities and colleges around the world. Innovations in education make it easier, more accessible and more fun for students to learn — and for professors to educate the next generation of engineers. The rapid pace of interdisciplinary, collaborative academic research is directly (and indirectly, through relationships with industry) reshaping our daily lives in ways we could not have imagined a decade ago. More students participate in the challenge of gaining engineering knowledge today than ever before. In the classroom, in the lab or during student competitions, computer-aided simulation is a vital tool in engineering education. Our latest issue of ANSYS Advantage magazine features how the academic world uses engineering simulation. Continue reading

What’s New with Contact Technology in ANSYS 15.0?

contact technology ansys 15Contact technology is used extensively throughout ANSYS Mechanical and Mechanical APDL to enforce compatible behavior between different portions within a model. With each Release, ANSYS continues to improve the breadth and robustness of our contact technology.  In ANSYS 15.0, we have enhanced contact still further to help users build models more efficiently without compromising on robustness.

Trim Contact, first introduced in ANSYS 14.5, is a great tool for reducing the number of unnecessary contact and target elements in large assemblies. In ANSYS 15.0, we have changed the default to activate trim contact even for application involving large deflection.

Today’s automotive community is increasingly called upon to think strategically and form unique relationships that expand its reach in a new era of cross-industry collaboration. We’re eager to share our excitement about Reaction Design’s new role at ANSYS (especially as it applies to developing optimal auto combustion processes) and reveal our shared vision for our more powerful and predictive simulation technologies.

We’re looking forward to telling you about it at the upcoming SAE 2014 World Congress and Exhibition, being held April 8 through 10 at Detroit’s Cobo Center. A must-attend for the automotive engineering community, this event represents an unparalleled opportunity to explore new technology through both technical sessions and the Innovators Only Exhibition.

Circuit Simulation Now Included in ANSYS HFSS for More Efficient Electronic System Design

Today, we announced that our ANSYS HFSS users can reduce design time and cost, while optimizing complete electronic system performance, thanks to linear circuit simulation embedded within the latest version of this software.

Designer SIWaveAt a high level, a more streamlined simulation workflow enables engineers to focus on enhancing complete system reliability and signal quality as well as analyzing electromagnetic interference. New HFSS product options for radio frequency (RF) and signal integrity (SI) analyses are also available — making high-frequency (HF) and high-speed electronic device design even more comprehensive.

The State of the Art for Electric Motor Design

Have you noticed that electric machines are everywhere these days? They are present in industrial equipment, cars, planes, household appliances, computers, mobile devices and more. The applications for both large and small motors are just exploding. Power transfer technologies in airplanes, such as the central hydraulic system and flight control actuation, are being replaced with electric motors. Electric and hybrid electric vehicles are powered by electric motors. When you put your phone on vibrate, the pulsation is created by an electric motor! The increased use of electric machines is driven by the global demand for more-automated and power-efficient products. The key is to find a better process to take an electric motor design from start to end. Continue reading

Workbench CAD Readers for ANSYS ICEM CFD Meshing

ANSYS ICEM CFD has been using the Workbench CAD readers for a few years now, and for those of you using ICEM CFD in Workbench, it is drag and drop simple. But many of our stand alone ANSYS ICEM CFD users are not really aware of this functionality, so here is a blog about it.

ANSYS ICEM CFD import

In previous versions, we had the Workbench readers under “File => Workbench Readers”. The Workbench readers really supersede the old ANSYS ICEM CFD readers. They are up-to-date, easy to use, and offer connections such as JT Open and SpaceClaim that ICEM CFD never supported on its own. Talking to users, we found that many thought the Workbench readers option would only work inside Workbench or if they installed Workbench. To make the option more obvious, we moved the Workbench readers to the top of the list and renamed it “Import Model.”

Why “Import Model” instead of “Import Geometry”? Because the Workbench readers also support mesh formats! You can even select a *.wbpj and get both the geometry and mesh. During the import process, you can filter to make it easier to find the files that you are looking for. For instance, you can switch it to SpaceClaim to filter for SpaceClaim documents. Select your particular file (some formats will show you a preview of it), and click Open. Continue reading
