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