OMPython openning files associates with non default OM libraries

[jeduapf]

Hello,

I am trying to open one file VSC_Test.mo that I developed using three
default Modelica libraries (Modelica 3.2.3,Complex 3.2.3,ModelicaServices
3.2.3) and 2 other libraries (OpenIPSL,HVDCcomponents). However when I try
to create the model mod using the function ModelicaSystem(), several
errors pop up. If I load the model only using the name of the file and its
path :

`
from OMPython import OMCSessionZMQ
from OMPython import ModelicaSystem

path = 'C:/Users/j.alves/Desktop/Stage/Python_CODES/Modele_HVDC_simplifie'
within = 'HVDCcomponents.Examples'
name = 'Test_VSC'

file ='"'+ path + '/' + name + '.mo'+'"'
mod_file = path + '/' + name + '.mo'
load_file = "loadFile(" + file + ")"
within_name = within + '.' + name

omc = OMCSessionZMQ()

mod = ModelicaSystem(mod_file)
mod.buildModel()

Load = omc.sendExpression(load_file)
if (not Load):
raise NameError("Coudn't load file")

If instead of using only the name I put "within" in "mod =
ModelicaSystem(mod_file,within_name)" since there is a commented within in
the VSC_Test file, I get:

Also, the paths were those libraries are is the same as the path of all
default libraries in MODELICAPATH (added to environmental variables )

Basically I want to open the VSC_Test.mo file and run simulations to get
the results in real time with python to then change the inputs and run
more simulations and so on... I will update the inputs of the system based
on the outputs.

Moreover, using only the library Modelica I can run all the simulations I
want using the "mod", but with these other 2 libraries I always get one
kind of error. Please help me with this issue...
