Modelica Buildings Library Data Center Example Fails

asked 2023-11-09 06:37:11 -0600

updated 2023-11-09 08:01:26 -0600

Hi We are using Modelica Buildings Library version 10.0.0 with OpenModelica version 1.22.0 on Linux Mint 21.2. The installs of the Buildings Modelica Library and OpenModelica are clean installs.

OpenModelica works with some simple (no Buildings library) examples, plus a number of the Buildings Modelica Library examples also work with out any problem. For example, Buildings.Examples.ChillerPlant.DataCenter.ContinuousTimeControl is fine. We infer both our OpenModelica and Modelica Buildings Library installations are fine. However, the data center chiller example :

Buildings.Applications.DataCenters.Examples.IntegratedPrimaryLoadSideEconomizer

fails with and error:

This model works with the latest version of OpenModelica. See also https://libraries.openmodelica.org/br...

Your error message shows /var/lib/jenkins/ws/LINUX_BUILDS/tmp.build/openmodelica-1.21.2, so it looks like you are using OpenModelica 1.21 rather than 1.22.
