LMS' Pimento Rev 5.1 Sound And Vibration Analyzer -- Portable And Easy To Use

With Rev 5.1 of Pimento, LMS introduces an innovative sound and vibration analyzer solution that breaks new ground in modal and acoustic testing. Pimento features a new 4 and 8 channel step-in hardware configuration, combined with a comprehensive range of applications, revolutionary LMS PolyMAX modal parameter estimations and a set of pre-configured ISO and ANSI testing procedures. Also brand-new are Pimento's intuitive 3-click procedure operation and 5-minute procedure definition features, which save significant testing, analysis and reporting time, meaning more time can be spent on value-added engineering activities.

In addition, the tight integration with Microsoft Office makes it possible to quickly compile and share reports. Altogether, Pimento represents a complete solution, ideally suited for users who simply want to pull an analyzer off the shelf, switch it on, and start measuring.

To better respond to evolving customer needs, the offering of Pimento Rev 5.1 analyzers has been extended to satisfy the need for low-channel-count systems. Pimento's new 4 and 8-channel V/ICP hardware configurations currently represent few of the most attractive and most compact step-in packages available on the market, including a 4-channel microphone configuration.

Complementary to its fully interactive engineering and troubleshooting capabilities, Pimento Rev 5.1 releases a highly intuitive user interface, which enables operators to complete a test and analysis assignment in just 3 clicks - Measure, Analyze and Report - providing increased operator efficiency and enhanced data integrity. Pimento is an open system that, in case no standard procedure fulfills all required testing specifications, makes it possible to define a new procedure in less than 5 minutes, without the need for any programming. By default, Pimento Rev 5.1 analyzers include a library of pre-configured procedures, of which some are industry-standard ISO or ANSI tests. In addition,
LMS regularly extends this library with newly predefined procedures, which can be downloaded from the Pimento website free-of-charge, without requiring a product license or having to wait for a new Pimento software update.

By introducing the unique LMS PolyMAX curve fitter, Pimento Rev 5.1 underlines its leading edge in modal analysis. This integrated modal parameter estimator greatly simplifies the selection of poles, typically the most difficult step in modal analysis, by offering crystal-clear stabilization diagrams. To further improve its application coverage, capability and performance, Pimento introduces new innovations and enhancements in all application domains of its elaborate range of applications, which includes sound power, sound intensity, sound-source localization, sound absorption, whole-body vibrations and hand-arm vibrations.

Pimento Rev 5.1 tightly integrates with Microsoft Office to obtain higher efficiency in relation to user guidance, reporting and data exchange. All textual and graphics information that guide operators during each step of a testing procedure can be defined using one single Microsoft Word template. The tight integration with Microsoft Excel offers the capability to efficiently set up and customize Pimento reports, on top of the possibility to use Visual Basic report scripting. Excel can also be used to view reports after concluding measurements, allowing employees to perform standard Excel data operations and easily share reports with other concerned colleagues.

Pimento is just one of the many LMS products available for virtual prototyping. It is a "personal" analyzer for mobile professionals concerned with noise and vibration analysis. As portable and relatively easy as it is to use, it can handle most tasks in general data acquisition and digital signal processing, rotating machinery, structural analysis and acoustics, including sound power and sound intensity measurements. Starting with 4 channels, you can expand Pimento to handle up to 24 channels and its results are compatible with other LMS systems. Pimento is well-suited suited for users who literally want to pull a noise and vibration analyzer off the shelf, switch it on, start
measuring, and quickly produce a report. For an analysis product of this type, the three-click procedure operation and five-minute procedure definition features save huge amounts of testing, analysis, and reporting time. Much like what is happening in other areas of engineering analysis and simulation, Pimento is approachable and usable by a wider potential customer base than the traditional "specialist."

Bentley Releases Initial Survey Results Of AutoCAD Users

Bentley Systems has released the initial results of its open, ongoing survey of AutoCAD users facing forced retirement of their software by Autodesk.

Autodesk states on its Web site: "After January 15, 2005, Autodesk will no longer sell upgrades or crossgrades from any AutoCAD 2000i-based products or Autodesk Inventor Series 6. Additionally, Autodesk will no longer provide technical support, apart from existing maintenance patches that are downloadable from

In less than a week, more than 2,000 people responded to the survey and were asked whether they agreed or disagreed with four statements. The results are as follows:
  • 87 percent agreed or strongly agreed: "I want my software vendor not to disrupt my project workflow by forcing me to upgrade or retire my software product."
  • 90 percent agreed or strongly agreed: "I want my software vendor to supply my team with free viewers so we can easily access and exchange project data."
  • 93 percent agreed or strongly agreed: "I want an open solution that allows me to participate in all types of projects and work with all CAD file formats and versions."
  • 92 percent agreed or strongly agreed: "I want to create PDF deliverables of my projects so I can freely share engineering and construction information."
  • Also, when asked whether they were interested in a platform that supports both DWG and DGN projects, 89 percent indicated they were.

    A spreadsheet of these results can be downloaded at

    The markets represented by the respondents were: building (design, construction, and operation), 28 percent; geospatial (communications, government, utilities, and mapping), 16 percent; industrial and process plant, 23 percent; civil (rail, road, and site), 22 percent; and other markets, 11 percent.

    Bentley is studying the results of the survey and formulating a program to address the concerns of these users. More AutoCAD users are invited to add their opinions to the survey at

    Well, I guess AutoCAD users have spoken - at least 2,000 of them anyway. But what are they really saying? For several years now Bentley has been trying to persuade AutoCAD users to come over to their side(as have several other competitors). The effort really began with its flagship product, MicroStation, that was the first non-Autodesk CAD application to read from and write to AutoCAD's native .dwg file format. Admittedly, the markets representing the respondents of this survey were mostly architectural and civil, but there was some response from mechanical users. This isn't too surprising, though, since virtually all of Bentley's business is in civil, architectural, and process plant
    design and engineering. Bentley did have a mechanical design product called MicroStation Modeler, but that product is long gone.

    While it is true that Autodesk does state on its Web site: "After January 15, 2005, Autodesk will no longer sell upgrades or crossgrades from any AutoCAD 2000i-based products or Autodesk Inventor Series 6," the company does offer a discount of 30% to users for upgrades going all the way back to R14.

    Bentley, along with many other CAD competitors have tried over the years to entice users to abandon AutoCAD with widely varying degrees of success. However, the fact remains, AutoCAD (full blown and LT, legal and pirated) are still today the most prevalent CAD packages out there. And while customers do grumble, the majority seem to stick with what they've got and are reluctant to move to another package because of the relatively high costs associated with that move - initial purchase, learning curve, lower productivity, file incompatibility, etc. This reluctance, though, won't discourage the competition from continuing to garner new customers from the AutoCAD user base.
