Hi Mathieu,
Sorry, I am fairly unaware, and confused, on how to share data from paraview.
On the bright side, I just found out my issue while trying to reproduce the case to send it to you.
I was applying the particle tracer directly on my “initial” foam file. Instead, I just tried to apply it on the temporal interpolator filter as the source, and it works! Sorry for the complicated thread while the solution was fairly straightforward.
To be a bit more clear, let me explain what I am trying to do.
I would like to create “fake” time steps. Right now, what I am doing is loading twice the same timestep, but “faking” paraview into thinking they are different, by simply copying my folder “200” to “300” and reloading. I then apply a temporal interpolator to get the deltaT I like.
I do understand that this is highly inneficient, because through the interpolator, a lot of calculation are made for interpolating between two state that are exactly the same. But I am not sure if there is a better way to go, I could deep dive into the code and try to create a modified TemporalInterpolator so that it does not recalculate the field between the timesteps, but that seems quite a daunting task for a beginner. Would you have a better way in mind?
Thanks again!
