Modeling Raised Floor Data Centers, Part 1

In this video, viewers will learn how to model raised floor data center designs. CoolSim is an intuitive, easy to use, yet powerful CFD modeling tool designed to optimize data center cooling and energy consumption. By leveraging Ansys' industry-leading simulation suite through a SaaS model, CoolSim enables the most cost-effective easy to use CFD modeling for data center operators and engineers. CoolSim is developed by Applied Math Modeling Inc., whose expertise in modeling the built environment with CFD has been consulted for a wide range of projects. These include design of data centers, clean rooms, indoor water parks, and more. If you are interested in our services, please reach out to [email protected] for business inquiries.
