3276	createNonlinearResidualEquationsComplex failed for fluid-model	Per Öberg	somebody	"Problematic library: https://github.com/droberg/Modelica-MVEM.git

The library mentioned above contains three test-models of which two simulates great (same results as in Dymola) while the third has problems with '''createNonlinearResidualEquationsComplex'''

The examples that are working in openModelica 1.9.2 (And nightly r25516) are:

* energyPreservationTest.mo
* throttleSanityCheck.mo

The example that is not working is
* SIEngineTest


Code to reproduce:

{{{
cd(""C:/Temp/Modelica-MVEM/MVEMLib"")
clear()
loadModel(Modelica);
loadFile(""package.mo"")
instantiateModel(MVEMLib.Examples.SIEngineTest)
simulate(MVEMLib.Examples.SIEngineTest, stopTime=15, method=""dassl"", tolerance=1e-005)
}}}


Result:
