__________________________________________

When using IBPSA ⇒ Fluid ⇒ HeatExchangers ⇒ ConstantEffectiveness, there are several parameters availabe like eps, m1_flow_nominal, m2_flow_nominal etc. to configure.

For Calibration: When using Dymola's File ⇒ Libraries ⇒ Design (1.1.1) and the according function Design ⇒ Calibration ⇒ calibrateSteadyState to calibrate the model only following parameters are available for "tuning parameters":
-) bal1 ↦ preDro ↦ sta_default ↦ p, T
-) bal2 ↦ preDro ↦ sta_default ↦ p, T
-) delta
-) eps
…but no m1_flow_nominal and no m2_flow_nominal.

Is there a possibility to have m1_flow_nominal and m2_flow_nominal available as tuning parameters for calibration?
I tried deleting "protected" and "final" attributes of e.g. "m1_flow_nominal" in the source code in all used packages/models without result.

Source Code attached.
