关于客户
Engrana LLC 成立于 2009 年，是一家计算流体动力学 (CFD) 和热分析咨询公司，由 Bill Wangard 博士创立。该公司专门研究涉及传质、多相流、化学气相沉积和外部空气动力学的复杂流体流动问题。 Engrana 为各种大中型公司提供虚拟 CFD 分析师服务，使用 ANSYS FLUENT、COMSOL 和 OpenFOAM 等商业和开源 CFD 软件。此外，Egrana 使用 EES 和 MATLAB 等数学工具开发定制的数学集总模型解决方案。该公司的客户遍布各个行业，包括消费品、电力变压器、建筑材料、制药和 CVD 反应器。
挑战
Engrana 是一家计算流体动力学 (CFD) 和热分析咨询公司，在准备客户提供的用于分析的几何形状方面面临着重大挑战。客户通常会提供实体几何的 CAD 文件，其中通常包含许多与流动分析无关的细节。去特征化和简化实体几何体，以及分解几何体以生成高质量的六边形主导网格的过程是一项复杂且耗时的任务。在引入 SpaceClaim 之前，几何去特征的责任主要留给客户，这使得清理过程成为一项困难且迭代的任务。此外，客户经常希望探索 CFD 解决方案对几何变化的敏感性，这需要一种能够以最小的努力轻松合并这些变化的工具。
解决方案
Engrana 采用 SpaceClaim 作为为 CFD 分析准备实体几何的关键工具。 SpaceClaim 允许 Engrana 去特征化和简化实体几何体，以及分解几何体以生成高质量的六角形主导网格。它还能够从实体几何中提取流量，使客户摆脱几何清理的负担。此外，SpaceClaim 还用于执行 CFD 优化研究。它可以轻松地以很少的努力合并几何变化，从而允许按顺序解决设计变体，以确定相对于参数变化的最佳解决方案。这极大地帮助了设计的优化。 SpaceClaim 还集成到 Engrana 的工作流程中，允许直接操作和修改客户的几何形状，从而消除耗时的迭代循环。

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.
