VISI launches Reverse Engineering suite

The latest release of VISI from Vero Software includes a new module for reverse engineering, along with new and enhanced functionality for both CAD and CAM processes, specifically designed for the mold and die market. It allows a point cloud to be loaded either from a Hexagon Romer Absolute Arm or an external file and generates the desired, optimized mesh with special tools. This mesh can then be used as the starting point to create the relative surfaces through the modeling function or used as it is for machining purposes.

Biggest reasons engineers hate their CAD system

Darren Garnick of Onshape says that, in a recent CAD satisfaction survey of 230 design professionals, Engineering.com asked a very provocative question: What do you hate most about your CAD software? The research, sponsored by SOLIDWORKS®, revealed these four things that engineers and designers despise the most (in order of importance).

Optimize your product manufacturing cost analysis

Boothroyd Dewhurst, developer of internationally recognized Design for Manufacture and Assembly (DFMA) software, has released DFM Concurrent Costing, Version 3.0. Deployed as a cost-analysis tool for engineering and procurement teams, the latest software allows manufacturers to move beyond "price" models, based largely on past bids, to industrial cost models grounded in scientific test data and studies. The result is a highly reliable "should cost" view of the product that offers insight into hidden cost drivers and ways to optimize both design and production.

Fastest way to dry your hands? FloEFD investigates

Have you ever wondered what’s the fastest way to dry your hands when using one of those air-shooting hand dryers in a public restroom? Should you rotate your hands or leave them in one place? What position is most efficient? Proving that modeling everyday challenges is fun and insightful, Robin Bornoff from Mentor Graphics tackles these questions using the full-featured 3D fluid flow and heat transfer analysis simulation tool called FloEFD.

Everything you wanted to know about heatsinks

How well a heatsink performs depends on particular aspects of its design, such as the thermal conductivity of the material it's made of, its overall dimensions, fin type used, airflow rate, and system. A theoretical model can be used to predict performance, or it can be measured experimentally. But because of the complex 3D nature of today’s electronic systems, engineers often use the numerical method via computational fluid dynamics (CFD) to determine the thermal performance of a heatsink before prototyping. This informative blog post from Mentor features two on-demand webinars to run through the basics of heatsink design and considerations.

MapleSim provides new approach to tire modeling

To save time and money in the design and development of new vehicles, automotive manufacturers typically use models to simulate the dynamic relationship between tires and road surfaces. Ideally, a tire model must accurately simulate the dynamics of the system and allow designers to vary its parameters, and simulations must also execute quickly. But existing tire models have inherent drawbacks.

Vital welding and joining data for design and simulation

Granta Design has announced its new GRANTA MI tools for the management of vital material property data relating to welds and other joining techniques. This data is very valuable for automotive organizations seeking to ensure accurate design or simulation, but it is rarely systematically managed -- leading to inefficiencies, inconsistencies, and risk. Granta is working closely with leading OEMs and suppliers through the Automotive Material Intelligence (AutoMatIC) Consortium to create a new, ready-to-go, extensible information system that can ensure proprietary data related to welds or other joints is captured, traceable, searchable, and accessible. User organizations will save time and maximize returns from important intellectual property (IP).

3D inverse design helps military OEM develop unique cooling fans

A U.S.-based defense contractor, an original equipment manufacturer (OEM) of life support systems (LSS) for military applications, had a need for a custom fan to be integrated in its product line. With TURBOdesign1 from Advanced Design Technology (ADT), the company was able to bring the fan design process in-house and cut design time as well as production cost.

In developing the fan, engineers were challenged to develop a large air-flow-volume, low-pressure fan characteristic with high air velocities over the stator blades. In order to achieve the best aerodynamic efficiency, it was required to avoid separation at the stator while recovering the static pressure. No existing standard design was known that could satisfy the requirements to efficiency, size, and operating speed.

Reducing the fan noise was an additional design objective. Certain rotor design features were desirable to minimize fan noise: forward sweep of the rotor blades, plus reduced chord length at the shroud were to eliminate the possibility of vortices shedding off from the suction side of the rotor blades and hitting the next blade pressure side close to the trailing edge. Another desirable feature was positive blade stacking at the rotor blade tip to minimize losses and noise associated with the tip clearance.

Originally, the company evaluated several conventional fan design approaches, including all the available commercial codes for design of turbomachinery based on a direct design approach. The evaluation criteria included computer system requirements and associated hardware costs, the number of engineers needed to be involved in the design process, and the learning curve to produce new designs with a high level of confidence. ADT's TURBOdesign1 software came out the winner, in part because it did not require special hardware and, after just three weeks of initial training, engineers were able to tackle their first fan design case.

The design team used ADT's TURBOdesign1 3D inverse design code to introduce these new features and achieve rotor blade loading that produces the required flow and pressure rise at the lowest shaft power with a sufficient stall margin.

After completing and testing two different axial fan designs, the company engineers became more confident that their next designs would be successful. Examples of the resulting geometries of the stage are shown in Figures 1 and 2.

Figure 1. The resulting geometry of one of the axial flow stages designed by TURBOdesign1.



Figure 2. The final hardware model.



ADT's TURBOdesign1 inverse design code, used together with CD Adapco Star CCM+ computational fluid dynamics (CFD) software, has proven to satisfy all of the new design objectives.

"We found ourselves using all the features implemented in the TURBOdesign1 code," said the company's aerodynamics engineer. "In addition to specifying meridional geometry and blade loading, having the ability to specify custom blade thickness, stacking location, and stacking profiles was very useful in achieving good aerodynamic designs."

TURBOdesign1 output data was exported to a spreadsheet, and additional design parameters, like diffusion factor for axial fans, were evaluated during the design procedure. This gave the designers an even higher level of confidence early in the design process, before taking it to CFD for evaluation and prototype construction and testing.

The use of ADT's TURBOdesign1 software made it possible to design an entirely new cooling fan from scratch, starting only from design requirements. In the process, the company was able to eliminate the costs of using outside consultants, reduce the lead time for new turbo-machinery designs of this type, and produce its own designs in-house that are best suited to its application needs.

"We cannot put a dollar figure on our new ability to design our own fans," said one design engineer. "But, in our opinion, it's invaluable."
