4750	Simulation results obtained with the NF are scrambled up	Francesco Casella	Per Östlund	"After some recent commits to the NF, a lot of models from the MSL simulate successfully but fail upon verification, see e.g. [https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.2/files/Modelica_3.2.2_Modelica.Electrical.Analog.Examples.AmplifierWithOpAmpDetailed.diff.html Modelica.Electrical.Analog.Examples.AmplifierWithOpAmpDetailed]

Judging from the comparison of old and new results, it seems that the problem is not that the simulation is somwhat wrong, but rather than there are some mismatches between the variables and their names in the results.

There are also recurring [https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.2/files/Modelica_3.2.2_Modelica.Electrical.Analog.Examples.AmplifierWithOpAmpDetailed.err error messages], such as
{{{
Error: Could not read variable sineVoltage.v in file
Modelica_3.2.2_Modelica.Electrical.Analog.Examples.AmplifierWithOpAmpDetailed_res.mat.
Warning: Get data of variable sineVoltage.v from file

and also some information is reported in the log regarding the erroneously reported variables such as

This issue shows up in a lot of models and may explain why the number of models compiled with the NF that currently pass verification (26) is much lower than the number of models that pass simulation (48). Please have a look at that."	defect	closed	critical	2.0.0	New Instantiation		fixed		Adeel Asghar Willi Braun Lennart Ochel
