.Buildings.Fluid.BaseClasses.FlowModels.Validation.BasicFlowFunction_dp_DerivativeCheck2

Information

This model validates the implementation of Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp and its second order derivative Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp_der2. If the derivative implementation is wrong, the simulation will stop with an error.

Implementation

The pressure drop dp is increased non-linearly in order for the first and second derivatives in Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp_der2 to be non-zero during part of the simulation. This will ensure full code coverage of this function.
