| Dear all, I have a problem with simulation in E+, as indicated below: ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SolveAirLoopControllers: Maximum iterations (50) exceeded for VAV_PISO 3, at SANTIAGO_VER, 01/01 06:15 - 06:19 ** Warning ** SimHVAC: Maximum iterations (30) exceeded for all HVAC loops, at SANTIAGO_VER, 01/01 07:30 - 07:45 ** ~~~ ** SimFlags=[TFFFFFFF] AirLoops[T],ZoneEq[F],NonZoneEq[F],PlantLoops[F],CondLoops[F],ElecCircuits[F],PlantDemandLoops[F],CondDemandLoops[F]..F=ok,T=fail ** ~~~ ** HVAC Tolerance Flags=[0000000] Enthalpy[0],MassFlow[0],HumRat[0],Pressure[0],FlowQual[0],Energy[0],Temp[0]..0=ok,1=fail ** ~~~ ** HVAC Tolerance Values, Most Recent listed first ** ~~~ ** HVAC EnthalpyTol=0.000, MassFlowTol=1.638E-015, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=1.64E-015, EnergyTol=-3.793E-011, TempTol=0.00 ** ~~~ ** HVAC side outlet node=[229 - VAV_SUBTE -1 RETURN AIR OUTLET] ** ~~~ ** HVAC EnthalpyTol=1.354, MassFlowTol=1.231E-003, HumRatTol=2.5459E-008, PressureTol=1.E-011 ** ~~~ ** FlowQualTol=1.23E-003, EnergyTol=-26.281, TempTol=1.27E-003 ** ~~~ ** HVAC side outlet node=[228 - VAV_PISO 22 RETURN AIR OUTLET] ** ~~~ ** HVAC EnthalpyTol=1.455E-011, MassFlowTol=3.597E-014, HumRatTol=8.6736E-019, PressureTol=1.E-011 ** ~~~ ** FlowQualTol=3.60E-014, EnergyTol=-8.068E-010, TempTol=1.42E-014 ** ~~~ ** HVAC side outlet node=[227 - VAV_PISO 21 RETURN AIR OUTLET] ** ~~~ ** HVAC EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** HVAC side outlet node=[226 - VAV_PISO 3 RETURN AIR OUTLET] ** ~~~ ** HVAC EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** HVAC side outlet node=[225 - VAV_PISO 2 RETURN AIR OUTLET] ** ~~~ ** Plant Tolerance Flags=[00000000] Enthalpy[0],MassFlow[0],HumRat[0],Pressure[0],FlowQual[0],Energy[0],Temp[0],PlantFlowMassFlow[0]..0=ok,1=fail ** ~~~ ** Plant Tolerance Values, Most Recent listed first ** ~~~ ** Plant EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** Plant side outlet node=[76 - CHILLER CNDW DEMAND OUTLET] ** ~~~ ** Plant EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** Plant side outlet node=[71 - CHILLER CNDW DEMAND INLET] ** ~~~ ** Plant EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** Plant side outlet node=[76 - CHILLER CNDW DEMAND OUTLET] ** ~~~ ** Plant EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** Plant side outlet node=[71 - CHILLER CNDW DEMAND INLET] ** ~~~ ** Plant EnthalpyTol=0.000, MassFlowTol=0.000, HumRatTol=0.0000, PressureTol=0 ** ~~~ ** FlowQualTol=0.00, EnergyTol=0.000, TempTol=0.00 ** ~~~ ** Plant side outlet node=[76 - CHILLER CNDW DEMAND OUTLET] ** ~~~ ** Plant Flow Tolerance Values, Most Recent listed first ** ~~~ ** PlantFlowFlowTol=0.000 ** ~~~ ** PlantFlowFlowTol=0.000 ** ~~~ ** PlantFlowFlowTol=0.000 ** ~~~ ** PlantFlowFlowTol=0.000 ** ~~~ ** PlantFlowFlowTol=0.000 I am simulating a VAV system with chiller water. what could be the problem in the simulation?
