Mathcad Overview

• Lack of standardized process and tools to capture calculations and IP– Multiple tools and mediums for data discovery and analysis– Information is stored in multiple sources and locations– Limited support for Traceability

• Limited sharing and reuse of calculations and IP – Tedious process to search, compile and understanding how to apply the knowledge

• Easier to “reinvent the wheel” for new projects– Significant time to bring new resources “up to speed”

Challenges in Leveraging Engineering Knowledge

It all starts with capture – but how is it done today?

5

• Loss of IP (due to attrition)– Delays in getting new engineers fully up-to-speed and productive on design best practices

• Delayed and over-budget projects – Wasted time spent fixing calculation errors late in the design cycle or after product launch

• Lost market share and revenue– Calculation errors force product recalls or costly rebuilds– Not re-using corporate IP forces delays in time-to-market

• Inability to support and demonstrate compliance– Critical corporate IP stored in multiple systems must be manually assembled for submission to

regulatory bodies

• Higher costs due to prototypes and lost productivity– Optimized designs from earlier products lost and not re-used– Engineers spend unnecessary time ‘re-discovering’ critical corporate IP

Business Implications

Question: How does this scenario impact your business?

6

• Enables enterprises to:– Prevent loss of IP and improve knowledge capture– Optimize critical design and engineering processes– Improve product quality – Speed up their time to market– Improve compliance with regulations

• Allows engineers to quickly and easily:– Solve, document, share and re-use vital calculations – Combine text, math, graphs & images in a

single worksheet– Enable knowledge capture, data reuse,

and design verification

What is PTC Mathcad?

“Talented engineers are using Excel and getting serious errors of which they’re simply not aware. And errors build up more rapidly than you might expect.”

Dr. Alan StevensSpecialist, Mathematical Modeling & Simulation

Rolls-Royce

In the late 1960’s, Uni-Systems, LLC was established to develop moveable structures for aerospace giants such as Boeing Aircraft, American Airlines, and Cape Canaveral Air Force Station. Later, the company branched into the military, construction, entertainment, and, in more recent years, sports industries. Uni-Systems has designed, fabricated and installed the mechanization components for five of the last six retractable sports-stadium roofs built in North America

Uni-Systems Scores Big in Designing Retractable Stadium Roofs Using Mathcad

SOLUTION

“My favorite part of Mathcad is that it’s easy to use. Engineers new to the system can accomplish tasks in a matter of hours and become experts in two weeks. There are no special programming skills required.”

Mike Becker, Lead Mechanical Engineer, Uni-Systems

RESULT(S)

The Challenge

Unlike proprietary calculating tools and spreadsheets, Mathcad enables engineers to design and document engineering calculations simultaneously, with comprehensive applied math functionality and dynamic, unit-aware calculations. Even better, Uni-Systems encountered very little downtime getting up to speed using Mathcad. And, throughout the design process, the Uni-Systems team kept all calculations in Mathcad, resulting in easy-to-see – and share – calculations.

Design and build the first fully retractable, natural-grass playing surface in the United States. Uni-Systems’ design team needed to devise a way to move an 18.9 million-pound playing field in and out of the stadium at the touch of a button

BusinessWeek magazine voted University of Phoenix Stadium one of the ‘Top 10’ sports facilities in the world, and in 2007 the Arizona Republic named it one of the seven wonders of Arizona.

BUSINESS INITIATIVE

SAMHYUN PF (Korea) is a bridge construction company established in 1999. SAMHYUN has since become a leader in “preflex” bridge construction, with the experience and knowledge in all aspects of the business- from design to construction. Recently, SAMHYUN led the industry with the successful development of the ‘Precom’ girder technique- the latest composite method of bridge construction.

Accurate Engineering Calculations are Critical for BridgeDesign at SAMHYUN PF (Korea)

SOLUTION

“With Excel it took a long time to create a calculation worksheet. Not only have we saved 50% of our time in creating calculations, but we have improved verification and accuracy of our calculations with Mathcad.”

- Ji, Gu Sam, Vice Director of the Design Team

RESULT(S)

SAMHYUN PF uses Mathcad as a calculation verification tool for the girder calculation process. Mathcad is critical for its speed and minimal errors produced when creating the calculations behind these structures

With Mathcad, SAMHYUN has achieved better verification of calculations; Excel calculations often contained errors which could not be checked easily

With Mathcad, SAMHYUN’s engineers have saved over 50% of their time in creating calculations- allowing for their easy documentation and re-use

SAMHYUN has been able to create an automated calculation system for “Precom” using Mathcad

The engineers at SAMHYUN PF create their key engineering calculations with Mathcad, so that they document their calculations with ease and with less time then previously done in Excel
