slow and broken unit tests

2

The tests listed in the file [Resources/Scripts/skipUnitTestList.txt](https://github.com/UdK-VPT/BuildingSystems/blob/master/BuildingSystems/Resources/Scripts/skipUnitTestList.txt) take very long to simulate or are broken (i.e. BuildingsPy cannot parse them). Could everybody please check whether you created one of the...

clean up SmoothFunctions

5

We should check the subpackge BS/Utilities/SmoothFunctions. https://github.com/UdK-VPT/BuildingSystems/tree/master/BuildingSystems/Utilities/SmoothFunctions All functions that are usefull should get a documentation, a corresponding block and a runnable example with reference results. Then they can be...

The connector `BuildingSystems.Interfaces.RadiationPortGeneral` has 3 potential variables (no prefix) and 0 flow variables (prefix flow), making it a non-physical connctor: https://www.modelica.org/events/modelica2008/Proceedings/sessions/session1a3.pdf The same is true for some more connectors, e.g....

BESTEST

3

We could and should validate our building models against BESTEST https://en.wikipedia.org/wiki/Building_Energy_Simulation_Test http://dx.doi.org/10.1016/S0378-7788(02)00072-5

clean up MoistAir functions

1

The subpackage BS/Utilities/MoistAirFunctions: https://github.com/UdK-VPT/BuildingSystems/tree/master/BuildingSystems/Utilities/MoistAirFunctions has some duplication with Annex60/Utilities/Psychrometrics: https://github.com/iea-annex60/modelica-annex60/tree/master/Annex60/Utilities/Psychrometrics and possibly also with Annex60/Media: https://github.com/iea-annex60/modelica-annex60/tree/master/Annex60/Media We should check our package to see what functions are missing in Annex60.

Units in HAM.HeatAndMoistureTransport

1

``` Advanced.PedanticModelica:=true; checkModel("BuildingSystems.HAM.HeatAndMoistureTransport"); ``` Looks like there are some units wrong.

Hi, does this package also support creating pseudorandom sequences? https://en.wikipedia.org/wiki/Low-discrepancy_sequence Thanks, Matthis

communication Modelica ↔ Unity

5

At UdK Berlin (@UdK-VPT, @jraedler, @nytschgeusen) we work on visualization of building simulation results and for this, we are interested in communication between Modelica and [**Unity**](https://unity3d.com/). This communication could be...

Here, the single-phase definition was used, but that is not correct for two-phase.

there are two if-conditions that used a different value: 1 versus 0.9999999999 this PR makes sure the identical limit is used this is a follow-up for #3885
