Free (standard conforming) library to model mechanical (1D/3D), electrical (analog, digital, machines), magnetic, thermal, fluid, control systems and hierarchical state machines. Also numerical functi...
Too often, I have been bitten by the hidden gains in blocks such as `Integrator` and `Add`, where unit errors are absorbed by inferring unexpected units for these gains with...
https://doc.modelica.org/ still displays v4.0.0 but should be bumped to v4.1.0.
I wanted to redesign the parameterization of Chua's Circuit to realistic values (mH instead of H, nF instead of F) and explain how the nonlinear resistor called Chua's diode can...
There was some discussion [here](https://github.com/modelica/ModelicaStandardLibrary/issues/4333#issuecomment-2414716442) about `Modelica.Electrical.Machines.Examples.InductionMachines.IMC_YD` being numerically extremely challenging when touching the tolerance. We now see this for System Modeler even with the tolerance that is set in...
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...
Fix typo
As reported by https://github.com/modelica/ModelicaStandardLibrary/actions/runs/13351228193/job/37288029202#step:5:50 ## Summary by CodeRabbit - **Style** - Refined text for improved clarity in the numeric stability description.
This model is an equivalent to the rotational [IdealGear](https://github.com/modelica/ModelicaStandardLibrary/blob/master/Modelica/Mechanics/Rotational/Components/IdealGear.mo)
Power converter models of Modelica.Electrical.{Analog, PolyPhase, PowerConverters} typically use three parameters: `parameter SI.Resistance Ron(final min=0) = 1e-5 "Forward state-on differential resistance (closed resistance)";` `parameter SI.Conductance Goff(final min=0) = 1e-5 "Backward...
The only controversial part is the name RaR. Without this change based on `La.L=250/(2*D*w)` and `C.C=(1/250)*D/w` one might conclude that `D` has unit Siemens (inverted Ohm). ## Summary by CodeRabbit...
