Problems with tolerance tubes at the end of the transient when the simulation result is longer than the reference one

2

The MSL contains some model with chaotic motion. The experiment annotation has a StopTime that allows to actually observe it, which is perfectly fine. However, it is of course futile...

Clarify the model extraction methodology using OMC

11

Currently, the generation of C code of a certain component for the Dynawo software from the Dynawo library is performed as follows: 1. the component is instantiated in a model;...

Models without parameter bindings nor explicit start modifiers are illegal in Modelica for simulation models

7

According to the Modelica Language Specification (MLS), [Section 8.6](https://specification.modelica.org/maint/3.6/equations.html#initialization-initial-equation-and-initial-algorithm) > If a parameter has a value for the start-attribute, does not have `fixed = false`, and neither has a binding...

Converting Dynawo 1.7.0 to use MSL 4.0.0

8

The dependency of Dynawo on MSL 3.2.3 is really bad, as this library is now quite obsolete. MSL 4.0.0 was released in 2020, and MSL 4.1.0, which is fully backwards...

The current status when running the master version of Dynawo 1.7.0 with the latest nightly build of OMC is shown [here](https://libraries.openmodelica.org/branches/master/Dynawo_dev/Dynawo_dev.html). There are some pending issues, each of them possibly...

Regression with MSL 4.1.0 due to change of definition of Modelica.Constants.eps

1

**Describe the bug** It should be possible to use MSL 4.1.0 instead of MSL 4.0.0 for all recent versions of Buildings, since it's expected to be backwards-compatible. Today I found...

Add flexible beam component to the MultiBody library

2

Back in 2005, our PhD students Francesco Schiavo and Luca Viganò, under the supervision of my colleague prof. Gianni Ferretti, developed the model of an Euler-Bernoulli thin beam component compatible...

#4552 was fixed by #4553. We should add a test with a = 0 and b > 0 to ModelicaTest.Fluid.Dissipation.Verifications.PressureLoss.General.dp_volumeFlowRate_DPMFLOW that covers this specific case

Examples in Modelica.Fluid.Examples.TraceSubstances use 300 ppm as concentration of CO2 for fresh air. This value was good around 1920 but is now totally obsolete, recent measurements at Mauna Kea hover...

Electrical.Branches.LineConstantImpedanceWithBreakers contains spurious fixed = true attributes on discrete inputs

2

Check `PowerGrids.Electrical.Branches.LineConstantImpedanceWithBreakers`. The model has two conditional boolean inputs `breakerStatusA` and `breakerStatusB` which are connected to their internal protected counterparts breakerStatusInternalA and breakerStatusInternalB because of the old rules prohibiting to...
