Data Centre Simulation & Digital Twin Engineering
Mansim helps data centre developers, operators, MEP consultants, contractors and technology providers understand how cooling infrastructure will perform before changes reach the physical facility.
Our modelling spans the complete cooling chain, from processors, cold plates and high-density racks to data-hall airflow, CDUs, technology cooling loops, liquid cooling, direct-to-chip cooling, chilled-water networks, thermal storage and external heat-rejection plant. We combine CFD, hydraulic modelling, transient thermal analysis, multi-physics simulation and digital twins to assess cooling capacity, resilience and efficiency as one connected system.
Data Centre Engineering Challenges
High-Density and Hybrid Cooling Integration
AI and HPC are increasing rack densities and combining air and liquid cooling. These systems mustwork together as one integrated cooling architecture.
Hydraulic Capacity and Flow Distribution
Cooling capacity can be limited by pressure losses, pump performance, valve behaviour and unevenflow distribution across CDUs and racks.
Transient Cooling Resilience
Load ramps, equipment failures and control delays can create temperature excursions that steady-state analysis misses. Transient modelling shows how the system responds over time.
Stranded Capacity and Operating Efficiency
Recirculation, poor flow distribution and inefficient operation can leave cooling capacity unusedwhile increasing fan, pump, energy and water demand.
