Multi-Core Simulation Speed Enhancements: ApacheSim
Increase hourly annual simulation speed, by using IES’s ApacheSim simulation engine and the Parallel Simulation Manager feature by using more of the available cores on your computer.
In benchmarking tests on larger building models containing hundreds of zones, with mixed mode HVAC systems the speed ups can be as much as 85%, or your simulation will run in 15% of the time taken for a single core.
You can access this feature in the VE from the Tools menu. Select Preferences > Simulation Tab and ensure you turn off Legacy mode.
One ApacheSim license covers 4 cores. By adding a second ApacheSim license 8 cores can be utilised simultaneously, a third ApacheSim license will enable 12 cores to be utilised.
