modelBasicFlowFunction_m_flow_DerivativeCheck
Model that checks the correct implementation of the 1st order derivative of the flow function
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates the implementation of Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_m_flow and its first order derivative Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_m_flow_der. If the derivative implementation is wrong, the simulation will stop with an error.
