Maximum .mat file size that can be loaded in BuildingsPy? Buffer Error?

[Walshest]

Hi,
I am trying to run long simulations [months/years] within Dymola and do post processing in Python with BuildingsPy.

After my simulations in Dymola I have .mat files which are 16+ GB.

When running the code:

# Read the .mat file into Python
r=Reader(path_file_sim, "dymola")

I get the following buffer error:

Is there any recommendations / way to get around this? - Other then removing the amount of variables in Dymola model.

What is the maximum file size that BuildingsPy could handle?
Is there a way of splitting the .mat file?
Are there other tools that could be recommended?
