Hi,
I’m visualizing an SPH simulation in ParaView using `.vtu` files with multiple time steps.
I would like to plot the time evolution of a variable ( like pressure or Z-variation because it’s a fluid simulation) at a fixed spatial point.
I tried using `Probe Location` and `Plot Data Over Time`, but I only get constant or zero values.
What is the best way to extract interpolated time series data at a given point in SPH simulations?
thank you in advance .

i shared the .pvd files ( i think they are the same as the .vtu files )

You need to share the .vtu files too.

here i shared the .vtu files ( SPH files took a lot of time to be imported so i shared another files with the same prob)

You need to provide access to the file

Works fine here, which version of ParaView are you using ?

version 5.13.3
Now I’m not sure if I used the filters properly , from the résults you got , is it possible to plot a simple graph of ‘H’ over the time in specific distance ?

Sure:
ProbeLocation + PlotDataOverTime

it’s working now , thank you
