Strange reference file to verify the results of the model Buildings.Controls.OBC.CDL.Routing.Validation.RealVectorReplicator

[AndreaBartolini]

The model Buildings.Controls.OBC.CDL.Routing.Validation.RealVectorReplicator fails the verification with the reference file produced by Dymola for the following signals:

• reaRep.u[1]
• time

The first is connected to the output of a ramp generator, the second is the current simulation time.

I run the model in both Dymola 2024 and OpenModelica v1.24.0 and the signals listed above are as expected, the problem is in the reference file that seems to contain strange values (I get this values from the OpenModelica CI):

Can you please check the values in the original reference file? Thanks in advance.

Keep @casella in the loop...

@AndreaBartolini I copied the line that starts with time from the file https://simulationresearch.lbl.gov/ReferenceResults/modelica-buildings/master/Dymola/Buildings_Controls_OBC_CDL_Routing_Validation_RealVectorReplicator.txt into the script:

import numpy as np
import matplotlib.pyplot as plt
time=[0e+00, 2.000000094994903e-03, ...]
plt.plot(time)
plt.show()

and got the plot below.

I see nothing wrong with the data.

Similarly if I plot time and reaRep.u[1]:

@mwetter thanks for the cross check, we will check the reference files used in the CI. @casella , who can do the cross check with the files indicated in https://github.com/lbl-srg/modelica-buildings/issues/3852#issuecomment-2150646446 ?

I'll open a ticket about that on the OMC issue tracker.
