Correct way data loading

Hello, i am trying to load data during experiment. Every 10 minutes i have got a new small vtu file with the same sample but new computed model of water saturation conditions. Is there correct way to load these data automatically ?
I have tested one way, to load data set with 20 dummy files and replace it on server where the pvserver works during experiment, yes it works, but i think it must be another correct way to update data and render it. I dont know exactly how long experiment will be, so i have got more than 20 files then it finished. Please advise.
