ERROR  : solver: DASSL: failed step at t = 79227.525123: In InjectionTwoWayVariableReturn.loaOpe.loa.coi.heaCoo.vol.steBal:
   The heat flow rate equals nan W and the mass flow rate equals 0.000001 kg/s,
   which results in a temperature difference nan K > dTMax=200.000000 K.
   This may indicate that energy is not conserved for small mass flow rates.
   The implementation may require prescribedHeatFlowRate = false.
