The Challenge
Engrana, a computational fluid dynamics (CFD) and thermal analysis consulting firm, faced a significant challenge in preparing customer-supplied geometries for analysis. Clients would typically provide CAD files of solid geometry, which often contained many details that were not relevant to the flow analysis. The process of de-featuring and simplifying the solid geometry, as well as decomposing the geometry to produce high-quality hex-dominant meshes, was a complex and time-consuming task. Before the introduction of SpaceClaim, the responsibility of geometry de-featuring was primarily left to the clients, making the cleanup process a difficult and iterative task. Furthermore, clients often wanted to explore the sensitivity of the CFD solution to geometrical changes, which required a tool that could easily incorporate these changes with minimal effort.
About The Customer
Engrana LLC, established in 2009, is a computational fluid dynamics (CFD) and thermal analysis consulting firm founded by Bill Wangard, Ph.D. The company specializes in complex fluid flow problems involving mass transfer, multiphase flow, chemical vapor deposition, and external aerodynamics. Engrana serves a variety of medium- and large-sized companies as their virtual CFD analyst, employing commercial and open source CFD software such as ANSYS FLUENT, COMSOL, and OpenFOAM. In addition, Engrana develops customized mathematical lumped-model solutions using mathematical tools such as EES and MATLAB. The company's customers span a diverse spectrum of industries, including consumer goods, electrical power transformers, construction materials, pharmaceutical, and CVD reactors.
The Solution
Engrana adopted SpaceClaim as a key tool for preparing solid geometry for CFD analysis. SpaceClaim allowed Engrana to de-feature and simplify the solid geometry, as well as decompose the geometry to produce high-quality hex-dominant meshes. It also enabled the extraction of flow volumes from the solid geometry, freeing clients from the burden of geometry cleanup. Additionally, SpaceClaim was used to perform CFD optimization studies. It made it easy to incorporate geometry changes with very little effort, allowing design variants to be solved in sequence to determine the optimal solution with respect to the changes of the parameter. This greatly aided in the optimization of the design. SpaceClaim was also integrated into Engrana's workflow, allowing the manipulation and modification of clients’ geometry directly, thereby eliminating time-consuming iteration loops.

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Improving Vending Machine Profitability with the Internet of Things (IoT)
The vending industry is undergoing a sea change, taking advantage of new technologies to go beyond just delivering snacks to creating a new retail location. Intelligent vending machines can be found in many public locations as well as company facilities, selling different types of goods and services, including even computer accessories, gold bars, tickets, and office supplies. With increasing sophistication, they may also provide time- and location-based data pertaining to sales, inventory, and customer preferences. But at the end of the day, vending machine operators know greater profitability is driven by higher sales and lower operating costs.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
