What CoolSim does
CoolSim, operated by Applied Math Modeling, Inc., is a cloud-based SaaS platform that applies computational fluid dynamics (CFD) specifically to data center airflow and thermal optimization. Founded in 2008 by former engineers from Fluent, Inc. (now Ansys) after the original tool was first developed in 2005, the company serves colocation/data center operators and design/build engineers who need to validate cooling capacity, identify hotspots, simulate equipment failures, and compare design alternatives (hot/cold aisle containment, raised/non-raised floors) before physical deployment. The product addresses a gap between general-purpose CFD tools that require deep technical expertise and the practical cooling decisions data center professionals face daily.
The platform combines a drag-and-drop model builder with predefined data center components (racks, CRACs, perforated tiles), automated mesh generation, and cloud-based Ansys Fluent solving. Users build geometry locally via a client application and submit models to the CoolSim Simulation Facility for processing, then receive automated output reports with temperature distributions, airflow patterns, and cooling efficiency metrics accessible from any internet-connected device. An Ansys Technology Partnership provides validated solver technology with over 40 years of industrial validation, eliminating the need for expensive local hardware or solver licensing. Adjacent offerings include an AutoCAD plugin, specialized CFD consulting services (campus-scale external flow, transient failure analysis, pollutant dispersion), and an extensive educational content library (10 whitepapers, 14+ webinars, training videos).
CoolSim operates a subscription-based SaaS revenue model with quote-based pricing and a 30-day trial. The go-to-market is enterprise-focused with consultative sales, DCEP-certified specialist support, and a Quick-Start onboarding program. The company has 1-10 employees, is privately held and bootstrapped, raised a single small funding round of $109,999 in 2012, acquired Active Modules in 2011, and lists Rogers, Telios PC, HED, and Modular Data Centers as named enterprise customers. Paul Bemis serves as President and CEO.

CoolSim product offering
Product offeringCore offering
CoolSim is a cloud-based SaaS CFD (Computational Fluid Dynamics) application purpose-built for data center airflow and thermal optimization. Users design data center geometry via a local drag-and-drop client app, then submit jobs to the CoolSim Simulation Facility, which runs the Ansys Fluent solver in the cloud for automated meshing, solving, and post-processing, producing temperature distributions, airflow pathlines, and efficiency reports. The company also offers specialized CFD consulting for campus-scale external flow, transient failure analysis, and pollutant dispersion scenarios.
Product overview
CoolSim is a unified SaaS CFD (Computational Fluid Dynamics) application for data center airflow and thermal optimization. The core product combines an intuitive drag-and-drop model builder with cloud-based Ansys Fluent simulation, delivering automated output reports and DCEP-certified expert support. The portfolio includes the main CoolSim application (local client app + cloud simulation pipeline), the CoolSim Output Report feature, Quick-Start onboarding program, Specialized CFD Consulting services (campus-scale external flow, transient failure analysis, pollutant dispersion), and educational resources (training videos, 14 webinars, 10 technical whitepapers, and example models). The product is delivered through an Ansys Technology Partnership, leveraging Ansys Icepak and Fluent solvers with over 40 years of industrial validation. CoolSim targets colocation/data center operators and design/build engineers with a 30-day trial and flexible subscription model.

CoolSim competitors and assessment
Company assessmentBroad incumbents
- Autodesk: Autodesk's CFD (formerly within the Autodesk Simulation portfolio) is a general-purpose fluid and thermal simulation tool used by AEC and mechanical design professionals. It overlaps with CoolSim's design/build engineer user base, especially given CoolSim's AutoCAD integration.
- Cadence Design Systems: Cadence acquired NUMECA (now Cadence Reality DC / Fidelity CFD) and offers electronics cooling and CFD simulation tools that overlap with CoolSim's data-center use cases at the system-thermal level, serving a broad EDA and electronics customer base.
- COMSOL: COMSOL Multiphysics is a widely used general-purpose simulation platform with a Heat Transfer / CFD module. While not data-center-specific, COMSOL competes for the same engineering buyer that might otherwise adopt CoolSim and is frequently used for thermal modeling across industries.
- Ansys: Ansys is the broader CFD/simulation incumbent whose Fluent and Icepak solvers power CoolSim's engine. Ansys Icepak is itself a direct data-center thermal simulation tool and competes head-on with CoolSim at the application layer, while Ansys also provides the underlying technology via the Technology Partner relationship.
- Siemens Digital Industries Software: Siemens offers Star-CCM+ and the legacy Flotherm (now Siemens Simcenter Flotherm) for electronics and data center thermal/CFD analysis. Like Ansys, Siemens is a broad simulation incumbent that competes with CoolSim in the data-center thermal vertical while also serving many other industries.
Emerging players
- SimScale: SimScale is a cloud-native SaaS platform for CFD, FEA, and thermal simulation, including HVAC and indoor airflow use cases. It competes with CoolSim on the cloud-delivery, no-local-license dimension but from a general-purpose rather than data-center-specialized angle.
- Rescale: Rescale provides a cloud HPC platform for running engineering simulations, including CFD workflows with Ansys, Siemens, and open-source solvers. It competes with CoolSim at the cloud-simulation-infrastructure layer rather than the application layer, and is complementary to CoolSim's solver dependencies.
- Menthera: Menthera is a niche simulation and consulting firm focused on data center thermal modeling and CFD-based optimization services. It overlaps with CoolSim's consulting offerings (campus-scale external flow, transient analysis) and competes for some of the same design/build engineering customers.
Others
- Nlyte Software: Nlyte is a DCIM (Data Center Infrastructure Management) platform used by colocation and enterprise operators to manage capacity, assets, and workflows. It is adjacent rather than directly competitive — but as DCIM platforms increasingly add thermal analytics, Nlyte represents a potential integration or substitution vector versus CoolSim.
Direct peers
- Future Facilities: Future Facilities offers 6SigmaDC, a digital twin / CFD simulation suite purpose-built for data center thermal and energy optimization. It is the closest direct competitor to CoolSim, targeting the same colocation operators and design-build engineers with a similar SaaS-style simulation workflow.
