Read and show connections

[plussss190]

I am trying to extract data related to connections from output file of TOUGH2.0/PetraSim.
And after that I want to visualize these data as vector in ParaView.
I don't know if I can do it with toughio, or is there any better way?

File:
Sensitivity.txt
(I change extension as .txt for upload)

Command:
toughio-extract -c Sensitivity.out MESH

Error code:
Traceback (most recent call last):
