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's capabililties, our experts deliver tailored models to meet your client's demands.
🌬️ Campus-Scale External Flow Modeling
Simulate wind-driven air movement across entire data center campuses—optimizing building layout and placement of generators and chillers for maximum performance.
⏱️ Transient Internal Flow & Thermal Failure Analysis
Capture time-dependent rack thermal behavior during cooling interruptions—predict temperature rise, hotspot locations, and recovery times to inform redundant designs and emergency protocols.
🏠Pollutant Dispersion for Critical Facilities
Model dispersion of airborne contaminants—diesel exhaust, chemical releases, or particulate matter to assess safe setbacks, stack heights, and environmental impact.
