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")

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...
