This model validates the implementation of IDEAS.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp and its second order derivative IDEAS.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp_der2. If the derivative implementation is wrong, the simulation will stop with an error.
The pressure drop dp is increased non-linearly in
order for the first and second derivatives in
IDEAS.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp_der2 to
be non-zero during part of the simulation. This will ensure full
code coverage of this function.
