Multiple errors while compiling the example BuildingsLibraryRoom

[salomehohl]

Describe the bug Simulation of the example BuildingsLibraryRoom fails. Tried multiple times on three different computers. All libraries were manually loaded in Dymola (without using Python).

To Reproduce Steps to reproduce the behavior:

1. In BESMod go to Examples.
2. Click on BuildingsLibraryRoom to open
3. Click the simulation button
4. 94 errors concerning IBPSA.Fluid.Movers occure

Expected behavior Simulation runs.

Screenshots

Simulation environment and version:

• Windows 10 Enterprise 22H2
• Dymola 4.0.0

First try:

• BESMod 0.3.1
• Aix Lib 1.3.1
• Buildings 9.1.0
• BuildingsSystem 2.0.0-beta
• IBPSA 4.0.0

Second try:

• BESMod 0.3.2
• Aix Lib 1.3.2
• Buildings 9.1.0
• BuildingsSystem 2.0.0-beta
• IBPSA 4.0.0

Additional context All the used libraries were reinstalled today. A new computer was also used where BESMod and IBPSA were never installed before. Similar errors occure while trying to run the other examples.

Thanks for the detailed issue!

Cloning the latest main and running the installation under Dymola 2023 works for me under Windows 10. What Dymola version are you using? And: What is the output of your installation process? Does it differ from this one?

The use of python is not possible at the moment, so all libraries were cloned manually and openend via the load button in Dymola. Thus no installation output is visible (except the loaded libraries). Dymola 2022 with Modelica version 4.0.0 was used.

[FWuellhorst]

Ok, that makes sense then! Can you manually checkout the following commits in the libraries?

"IBPSA": "3eb103a9fafb0ee718661ce6a97ae4f6fc8a99c0"
"AixLib": "3bc1bcd9b33c8991eb50aa8fb3913b6dac6a1a1e"
"Buildings": "fba63b60c75bb0285ede2081ae17dbdc9f38d9e7"
"BuildingSystems": "64adca47eae19d2744d86aa8d1624cbf7ad6326b"

With those, the simulation worked ( there are still warnings and messages) but the simulation time was around 15 minutes with the preset simulation setup of a whole year. Interval length of 600 seconds and integration algorith Dassl with a tolerance of 0.0001.

That's how the outputs look like. The information about the indoor temperature is not included in >output >building and when searching for it in the >building tab above, the result looks like this. Something is definitly not working there.

[FWuellhorst]

Regarding the simulation time: That is weird. For the paper, the simulation time was much lower. I get times higher than 5 months ago, for the buildings room 500 seconds and for the TEASER example 480 seconds. Depending on your device, this may be higher. Some error statistics are new which were not there last time I checked, in the ventilation subsystem. Do you need this subsystem?

Regarding the plot: The BuildingsLibraryRoom is rather a proof of concept that different libraries. If you check the free-floating temperature of the room in the Buildings Library (Buildings.ThermalZones.Detailed.Validation.BESTEST.Cases6xx.Case600FF), the temperature rise as well. The example contains no active cooling. Thats why we can't counter the high temperatures:

Thank you for the moment!
