modelBenchmarkFlowDistribution1
Performance benchmark of building heating water flow distribution modeling
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model is part of a computational performance benchmark between
- a simplified modeling of the piping network as implemented in Buildings.DHC.Loads.BaseClasses.FlowDistribution (see the corresponding example Buildings.DHC.Loads.BaseClasses.Validation.BenchmarkFlowDistribution1), and
- an explicit modeling of the piping network (see the corresponding example Buildings.DHC.Loads.BaseClasses.Validation.BenchmarkFlowDistribution2).
