CoolSim simulation pipeline
From room layout to pathline visualizations — four steps, one browser.
- 01
Create layout & geometry
Design the physical layout of your data center — racks, CRACs, room boundaries — on your local machine using the CoolSim client.
- 02
Meshing
Automatically generate a high-quality computational mesh tailored to your geometry.
- 03
Solution
Run the Ansys Fluent CFD solver to simulate airflow, temperature distribution, and thermal loads.
- 04
Post-processing
Visualize with heat maps, pathline plots, and performance indicators to fine-tune your layout.
For Colocation / Data Center Operators
CoolSim helps data center managers address two critical questions: Do you have sufficient cooling capacity for increasing IT loads, and where should you deploy additional equipment? Quickly develop CFD models to simulate normal operations and cooling unit failures, identify your most critical cooling units, and create comprehensive thermal management plans for your data center.
For Design / Build Engineers
Predict data center performance before implementation with CoolSim’s quick and easy CFD modeling. Assess IT load capacity, cooling unit failures, and compare design alternatives like hot/cold aisle containment and raised/non-raised floors. The automated CoolSim Output Report highlights key parameters for each scenario, helping designers present optimal solutions to customers based on reliability and cost.
Specialized CFD consulting
When your modeling needs go beyond CoolSim, our experts deliver tailored models for your client's demands.
Campus-scale external flow modeling
Simulate wind-driven air across entire data center campuses — optimizing building layout and placement of generators and chillers.
Transient internal flow & thermal failure
Capture time-dependent rack thermal behavior during cooling interruptions — predict hotspot locations and recovery times.
Pollutant dispersion for critical facilities
Model dispersion of diesel exhaust, chemical releases, or particulate matter to assess safe setbacks and stack heights.
