Biggest reasons engineers hate their CAD system

Darren Garnick of Onshape says that, in a CAD satisfaction survey of 230 design professionals last year, 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).

Get your CAD under control before implementing PLM

Despite the widespread adoption of PDM and PLM technology by large companies, the vast majority of companies below 20 designers have yet to implement these solutions and still just use shared drives to store their CAD files. Each year that passes without PDM/PLM is another year of CAD data becoming more disorganized, which makes it even more difficult to migrate to a new system. But some companies are turning to CAD geometry indexing and search technologies to better aggregate their existing CAD file shares. By Jon Gable, Adaptive Corporation

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.

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."
