@mtiller, [this report](https://libraries.openmodelica.org/branches/master/ModelicaByExample/files/ModelicaByExample_ModelicaByExample.Components.LotkaVolterra.Examples.ThreeSpecies_Quiescent.err) suggests that model ModelicaByExample.Components.LotkaVolterra.Examples.ThreeSpecies_Quiescent in your library actually tries to access protected elements. We introduced stricter checks in OpenModelica since 1.19.0, so this model stopped running there....

**Describe the bug** While scanning the OpenModelica test report of the [development version of Buildings 9.0.0](https://libraries.openmodelica.org/branches/master/Buildings_latest/Buildings_latest.html), I found that there are 18 models failing in the front end, vs. only...

@mwetter, I am trying to debug several ChillerCooled models that are currently failing in OpenModelica, e.g. [ ​Buildings.Applications.DataCenters.ChillerCooled.Equipment.Validation.HeatExchanger](https://libraries.openmodelica.org/branches/newInst/Buildings_7.0.0/files/Buildings_7.0.0_Buildings.Applications.DataCenters.ChillerCooled.Equipment.Validation.HeatExchanger.sim). When running it in OMEdit, I get the following diagnostic message ```...

The ModelicaTest library contains a large number of test cases that are meant to test the behaviour of components of the MSL. They can of course also help to assess...

The explanation of elsewhen in [Section 8.3.5](https://specification.modelica.org/master/equations.html#when-equations) is a bit confusing to me towards the end. The model DoubleWhenConflict is indeed erroneous, because it has an equation section, and the...

In [Section 16.4](https://specification.modelica.org/master/synchronous-language-elements.html#clocked-state-variables) I read the following statements: > A variable to which previous has been applied is called a clocked state variable. > >Operator 16.6 previous > > previous(u)...

clocked
clarification

Modelica library developers are converting their libraries to MSL 4.0.0, after almost 10 years of backwards-compatible MSL, when nobody bothered. This raises one fundamental question: what does _backwards compatible_ actually...

clarification

One can try to address the need to debug models using homotopy with this kind of wrapper functions. ```modelica model TestHomotopy Real y1, y2; function tilHomotopy "Extended TIL Homotopy function"...

Consider the following MWE: ```modelica package TestFunctionInputType record BaseR constant Integer n = 3; Real x[n]; end BaseR; record DerivedR extends BaseR(n = 5); end DerivedR; function f input BaseR...

Consider the following scenario - package A uses packages B and C - package B uses package D version x - package C uses package D version y - package...
