After #13380 was closed, if-equations with multiple equations in the form var = are not considered as a single strong components, but rather split into individual equations with conditional expression,...

The backend cannot split a large strong component into smaller components

Please check the [SOFCPoliMi.Tests.OpenModelica.BenchmarkCammarata](https://libraries.openmodelica.org/branches/master/SOFCPoliMi/files/SOFCPoliMi_SOFCPoliMi.Tests.OpenModelica.BenchmarkCammarata.err) test model with the declarative debugger. OMC finds an initial-lambda0 huge strong component 17280 with 1474 equations and 261 iteration variables. If we run the same...

Running automatic conversion scripts shouldn't screw up the formatting unnecessarily

We need to upgrade the Dynawo library from MSL 3.2.3 to MSL 4.0.0. My understanding is that the number of necessary changes to the source code of Dynawo should be...

Please run the following MWE: ```modelica model TestSparsityScalar Real x; equation x + exp(x) = 0; annotation(__OpenModelica_simulationFlags(nls = "kinsol")); end TestSparsityScalar; ``` The simulation crashes with: ``` Process crashed Simulation...

Apply the scaling factors of the function residuals when computing the Newton diagnostics

1

The \alpha and \Gamma indicators of the Newton Diagnostics algorithm require the computation of the Inf-norm (i.e., the largest absolute value of all its components) of the nonlinear residual r(x_0)....

Invalid generated C code in jac.c in Dynawo example: use of undeclared identifier

Heavyweight tests for Buildings

The model `Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SmallOffice.Guideline36Winter` is a good candidate for testing, in particular if you change ``` StartTime=432000, StopTime=864000, ``` to ``` StartTime=0, StopTime=31536000, // 1 year ``` This uses the EnergyPlus...

The NF should not flatten evaluated parameters with fill() bindings when -d=evaluateAllParameters --newBackend is set

As reported to me by @mscuttari. Consider the following MWE ```modelica model Test parameter Real x[10] = fill(5, 10); Real y[10]; equation y = x; end Test; ``` Flattening with...

Issue with quoted identifiers in records during code generation

Please consider this MWE: ```modelica model TestFluid package Fluid = SOFCPoliMi.Media.MainClasses.SOS_CO2.SOS10ComponentsModelica; Fluid fluid(p_start = 1e5, T_start = 300); equation fluid.p = 1e5; fluid.T = 300; fluid.X = 0.1*ones(10); end TestFluid;...

Jacobian generation in ScalableTestGrids tests does not generate the sparsity pattern

6

Follow-up of #12937. Jacobian generation in ScalableTestGrids tests does not generate the sparsity pattern. As a consequence, Type1_N_2_M_2, which has 10,000 equations, takes 0.16 to generate the Jacobian, while Type1_N_4_M_4,...
