When trying to run the model FluidSystemComponents.HydroThermal.Examples.test_hydroCylinder004 I get the following error:

Translation of FluidSystemComponents.HydroThermal.Examples.test_hydroCylinder004:

The DAE has 588 scalar unknowns and 588 scalar equations.

The equation
pumpConstQflow_ideal1.fluid_2.p = checkValveSpringLoad_Linear1.fluid_1.p;

constrains the continuous time variables:
The following variables are set in reinit clauses:
checkValveSpringLoad_Linear1.fluid_1.p
pumpConstQflow_ideal1.fluid_2.p

requiring them to be continuous time state variables.
It is necessary to modify the stateSelect attributes or the model.
