About The Customer
DSA is an ocean engineering consultancy and software company that provides solutions to marine service providers, project developers, ocean engineers, naval architects, oceanographers, and anyone with business in the water. The company's solutions enable these stakeholders to assess the effect of currents, winds, and waves on their vessels, technologies, and projects. DSA produces two advanced hydrodynamic marine analysis software packages, ProteusDS and ShipMo3D, and also provides a range of ocean engineering consulting services to marine businesses, often using ProteusDS and ShipMo3D.
The Challenge
DSA, an ocean engineering consultancy and software company, faced a significant challenge in creating high-quality hydrodynamic meshes and models for ship and marine structures. The task of creating high-quality meshes is a complex one in CAD software, as the mesh often isn't well conditioned for hydrodynamic solutions which require a closed surface for resolving hydrodynamic effects such as nonlinear hydrostatics and BEM solution. To build an accurate ship hydrodynamic model, ShipMo3D, one of DSA's software, requires the development of a mesh of the vessel hull. This could be achieved either through the creation of hull lines or through importing an OBJ mesh file created using third-party software. However, both these methods were time-consuming and often resulted in less than optimal meshes.
The Solution
To overcome this challenge, DSA turned to Altair HyperMesh to create these mesh files from CAD files in a fraction of the time it took to enter hull line data. Altair HyperMesh allowed DSA to adjust the mesh effectively and ensured the most efficient and accurate mesh was used. Once the mesh was imported into ShipMo3D, the software used a boundary element method, based on a paneled surface, to determine the hydrodynamic response of a ship to waves and motions. This allowed users to determine things like vessel pitch and roll response, vertical and lateral accelerations, and overall maneuvering and seakeeping characteristics. Similarly, ProteusDS, another software from DSA, used hydrodynamic meshes for the calculation of hydrodynamic loads. DSA also began using Altair AcuSolve and Altair Virtual Wind Tunnel on a routine basis as part of its consulting work, forming integrations in their software that allowed results of AcuSolve and VWT to be readily exported.

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

Vehicle Fleet Analytics
Organizations frequently implement a maintenance strategy for their fleets of vehicles using a combination of time and usage based maintenance schedules. While effective as a whole, time and usage based schedules do not take into account driving patterns, environmental factors, and sensors currently deployed within the vehicle measuring crank voltage, ignition voltage, and acceleration, all of which have a significant influence on the overall health of the vehicle.In a typical fleet, a large percentage of road calls are related to electrical failure, with battery failure being a common cause. Battery failures result in unmet service agreement levels and costly re-adjustment of scheduled to provide replacement vehicles. To reduce the impact of unplanned maintenance, the transportation logistics company was interested in a trial of C3 Vehicle Fleet Analytics.

3M Gains Real-Time Insight with Cloud Solution
The company has a long track record of innovative technology solutions. For example, 3M helps its customers optimize parking operations by automating fee collection and other processes. To improve support for this rapidly expanding segment, 3M needed to automate its own data collection and reporting. The company had recently purchased the assets of parking, tolling, and automatic license plate reader businesses, and required better insight into these acquisitions. Chad Reed, Global Business Manager for 3M Parking Systems, says, “With thousands of installations across the world, we couldn’t keep track of our software and hardware deployments, which made it difficult to understand our market penetration.” 3M wanted a tracking application that sales staff could use to get real-time information about the type and location of 3M products in parking lots and garages. So that it could be used on-site with potential customers, the solution would have to provide access to data anytime, anywhere, and from an array of mobile devices. Jason Fox, Mobile Application Architect at 3M, upped the ante by volunteering to deliver the new app in one weekend. For Fox and his team, these requirements meant turning to the cloud instead of an on-premises datacenter. “My first thought was to go directly to the cloud because we needed to provide access not only to our salespeople, but to resellers who didn’t have access to our internal network,” says Fox. “The cloud just seemed like a logical choice.”
