AbsoluteAngles sensor is not flexible enough

6

Consider the attached MWE: [TestAngleSensor.mo.txt](https://github.com/user-attachments/files/16037545/TestAngleSensor.mo.txt)  The body is connected to the fixed reference by a flange rotating around the z axis, while the rotation of the body is measured...

Improvements to the CSV compare tool for zero reference signals

12

While reviewing regressions from MSL 4.0.0 to MSL 4.1.0 (#4341) with @tobolar, we stumbled upon several reference signals which were very close to zero, but not exactly at zero due...

The models ``` ModelicaTest.Fluid.TestComponents.Pipes.DynamicPipeEnergyConservationCheck ModelicaTest.Fluid.TestComponents.Pipes.DynamicPipeEnergyConservationCheck2 ``` do not have fully specified initial conditions. These should be added to make sure that the initialization problem is not tool-dependent. This is probably...

Provide an explicit list of constructs which are legal in Base Modelica but not in Modelica

1

Base Modelica is _mostly_ a subset of Modelica, with some exceptions, which can lead to code that is valid Base Modelica but not valid Modelica. This is of course a...

Update ReadMe.md

1

Added a short explanation in the Roadmap on how to actually read the proposal, which is not obvious at first sight.

Are discrete inputs allowed in Modelica?

3

Follow-up of ticket OpenModelica/OpenModelica#12531 by @BasilioPV. Consider the following MWE: ```modelica model DiscreteIssue discrete input Real In(start=1); discrete output Real Out(start=0); equation when In>1 then Out=1; end when; end DiscreteIssue;...

Otherwise they will be assumed as impure by default. In fact, they are pure: if you call them with the same library string and the same input value, they are...

Division by zero caused by wrongly generated external object function call in Buildings.Fluid.HeatPumps.ModularReversible.Examples.LargeScaleWaterToWater_OneRoomRadiator

3

Please check [Buildings.Fluid.HeatPumps.ModularReversible.Examples.LargeScaleWaterToWater_OneRoomRadiator](https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Fluid.HeatPumps.ModularReversible.Examples.LargeScaleWaterToWater_OneRoomRadiator.sim) The simulation fails during initialization at lambda = 0 with ``` division by zero at time 0, (a=1) / (b=-0), where divisor b expression is: heaPum.P ```...

Potentially important min violation warnings are lost

1

Inspired by #12731, and possibly related to #10477. Consider the following MWE: ```modelica package MinErrorOrWarning model Test1 "This should generate a warning about delta being lower than it min attribute"...

The NB generated code does not and cannot use sparse Kinsol

The `ScalableTestSuite.Electrical.DistributionSystemDC.ScaledExperiments.DistributionSystemModelicaIndividual_N_10_M_10` model runs correctly with both the OB and NB. The model is stateless and contains a large nonlinear system with 519 unknowns. The [runtime performance with the OB](https://libraries.openmodelica.org/branches/master/ScalableTestSuite_noopt/files/ScalableTestSuite_noopt_ScalableTestSuite.Electrical.DistributionSystemDC.ScaledExperiments.DistributionSystemModelicaIndividual_N_10_M_10.sim)...
