.Buildings.UsersGuide.ReleaseNotes.Version_1_0_build2 .Buildings.UsersGuide.ReleaseNotes.Version_1_0_build2Version 1.0 build 2 has been released to correct model errors that were present in version 1.0 build 1. Both versions are compatible. In addition, version 1.0 build 2 contains improved documentation of various example models.
The following existing components have been improved in a backward compatible way:
| Buildings.Controls | |
| Buildings.Controls.Continuous Buildings.Controls.Discrete Buildings.Controls.SetPoints |
Improved documentation of models and of examples. |
| Buildings.Airflow.Multizone | |
|
Buildings.Airflow.Multizone.DoorDiscretizedOpen Buildings.Airflow.Multizone.DoorDiscretizedOperable |
Changed the computation of the discharge
coefficient to use the nominal density instead of the actual
density. Computing sqrt(2/rho) sometimes causes
warnings from the solver, as it seems to try negative values for
the density during iterative solutions. |
| Buildings.Airflow.Multizone.Examples | Improved documentation of examples. |
| Buildings.Examples.DualFanDualDuct | |
| Buildings.Examples.DualFanDualDuct.Controls.RoomMixingBox | Improved control of minimum air flow rate to avoid overheating. |
The following critical errors have been fixed (i.e., errors that can lead to wrong simulation results):
| Buildings.HeatTransfer | |
| Buildings.HeatTransfer.Convection.Exterior | Fixed error in assignment of wind-based convection coefficient. The old implementation did not take into account the surface roughness. |
| Buildings.ThermalZones | |
| Buildings.ThermalZones.Detailed.BaseClasses.SolarRadiationExchange | In the previous version, the radiative properties of the long-wave spectrum instead of the solar spectrum have been used to compute the distribution of the solar radiation among the surfaces inside the room. |
| Buildings.ThermalZones.Detailed.BaseClasses.MixedAir | Added missing connect statement between window frame surface and window frame convection model. Prior to this bug fix, no convective heat transfer was computed between window frame and room air. |
| Buildings.ThermalZones.Detailed.BaseClasses.HeatGain | Fixed bug that caused convective heat gains to be removed from the room instead of added to the room. |
The following issues have been fixed:
| Buildings.Fluid.Geothermal.Boreholes | |
| #45 | Dymola 2012 FD01 hangs when simulating a borehole
heat exchanger. This was caused by a wrong release of memory in
freeArray.c. |
| Buildings.ThermalZones | |
| #46 | The convective internal heat gain has the wrong sign. |
