Version 13.0.1
Extends from Modelica.Icons.ReleaseNotes (Icon for release notes in documentation).
Information
Version 13.0.1 is backward compatible with 13.0.0.
The library has been tested with Dymola 2026x, OpenModelica 1.26.3, OPTIMICA 1.66 and recent versions of Impact.
This backward compatible version contains various model improvements.
The following existing components have been improved in a backward compatible way:
| Buildings.Air.Systems.SingleZone.VAV.Examples.OptimalStart | |
| Buildings.Air.Systems.SingleZone.VAV.Examples.OptimalStart.BaseClasses.ZoneWithAHUConventional Buildings.Air.Systems.SingleZone.VAV.Examples.OptimalStart.BaseClasses.ZoneWithAHUG36 |
Changed the class type from block to model. This is for Buildings, issue 4606. |
| Buildings.HeatTransfer.Windows | |
| Buildings.HeatTransfer.Windows.BaseClasses.Overhang | Changed the class type from block to model. This is for Buildings, issue 4606. |
| Buildings.BoundaryConditions | |
| Buildings.BoundaryConditions.SolarGeometry.IncidenceAngle Buildings.BoundaryConditions.SolarGeometry.ZenithAngle Buildings.BoundaryConditions.SolarIrradiation.DiffuseIsotropic Buildings.BoundaryConditions.SolarIrradiation.DiffusePerez Buildings.BoundaryConditions.SolarIrradiation.DirectTiltedSurface Buildings.BoundaryConditions.SolarIrradiation.GlobalPerezTiltedSurface |
Changed the class type from block to model. This is for IBPSA, issue 2122. |
| Buildings.Controls.OBC.CDL | |
| Buildings.Controls.OBC.CDL.Integers.Change Buildings.Controls.OBC.CDL.Logical.Change |
Replaced initial equation with start attribute on input. This is for Buildings, issue 4581. |
| Buildings.Controls.OBC.CDL.Logical.Edge Buildings.Controls.OBC.CDL.Logical.FallingEdge Buildings.Controls.OBC.CDL.Logical.Pre Buildings.Controls.OBC.CDL.Logical.TrueFalseHold |
Replaced initial equation with start attribute on input. This is for IBPSA, #2136. |
| Buildings.ThermalZones.Detailed | |
| Buildings.ThermalZones.Detailed.Examples.FFD | Improved C source codes and recompiled FFD library to allow the examples being simulated with OpenModelica. This is for Buildings, #4015. |
| Buildings.Fluid.Sources | |
| Buildings.Fluid.Sources.BaseClasses.PartialSource Buildings.Fluid.Sources.BaseClasses.PartialAirSource |
Removed deprecated cardinality function.Removed protected parameter flowDirection as it was set to Bidirectional and had no effect on the model.
The annotation mayOnlyConnectOnce must not be used for these models as they are often used to set the
reference pressure in closed system flow networks.This is for Buildings, #4607. |
| Buildings.Fluid.Sources.TraceSubstancesFlowSource | Removed deprecated cardinality function and replaced with mayOnlyConnectOnce annotation.Removed protected parameter flowDirection as it was set to Bidirectional and had no effect on the model.This is for Buildings, #4607. |
| Buildings.ThermalZones.EnergyPlus_24_2_0 | |
| Buildings.ThermalZones.EnergyPlus_24_2_0.Validation.MultipleBuildings | Improved C source codes to allow the validation model being simulated with OpenModelica. This is for Buildings, #3345. |
| Buildings.ThermalZones.EnergyPlus_24_2_0.OpaqueConstruction | Removed deprecated cardinality function and replaced with mustBeConnected annotation.This is for Buildings, #4607. |
| Buildings.Utilities.IO.BCVTB | |
| Buildings.Utilities.IO.BCVTB.BaseClasses.FluidInterface | Removed protected parameter flowDirection as it was set to Bidirectional and had no effect on the model.This is for Buildings, #4607. |
| Buildings.Utilities.Psychrometrics | |
| Buildings.Utilities.Psychrometrics.TWetBul_TDryBulXi | Added nominal attribute for temperature. This is for IBPSA, #2155. |
The following uncritical errors have been fixed (i.e., errors that do not lead to wrong simulation results, e.g., units are wrong or errors in documentation):
| Buildings.Fluid.DXSystems | |
| Buildings.Fluid.DXSystems.Cooling.BaseClasses.Evaporation | Added missing variable assignment for unused variable in a branch that will not compute evaporation. This is for Buildings, #4715. |
| Buildings.Fluid.Geothermal.Borefields.BaseClasses.HeatTransfer.ThermalResponseFactors | |
| Buildings.Fluid.Geothermal.Borefields.BaseClasses.HeatTransfer.ThermalResponseFactors.gFunction | Initialized local variables A and B to avoid use of uninitialized elements
of a matrix. This update does not change the results.This is for Buildings, #4707. |
| Buildings.Fluid.HeatPumps.ModularReversible.BaseClasses | |
| Buildings.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialReversibleRefrigerantMachine | Corrected the flow reversal parameter in the condenser mass flow sensor
(allowFlowReversalEva was used instead of allowFlowReversalCon).
Also corrected the sensor description from evaporator to condenser.This is for IBPSA, #2162. |
Note:
- Added unit specification to various models to avoid a warning in Dymola 2025x.
