Hi, I want to visualize the results (vtk format) produced by an on-going simulation using Paraview concurrently. Is there any way to do this using Paraview? Is it possible to set up a timer so that I could write a python script to monitor and scan the folder for new results? Thanks.

This usecase , in-situ live visualization, is covered by our tool Catalyst. https://www.paraview.org/in-situ/ Do not hesitate if you any follow-up question.
