Hi,

I have time series data with 3 equidistant time steps. My data is the solution of a periodic problem and I wish to create an animation of the solution. I need to interpolate the data in time to produce the animation, however the TemporalInterpolator filter uses linear interpolation. I was looking for a way to interpolate the data in time using a fourier transform to maintain the periodic nature of the interpolated solution. I was wondering if there was a way to do this directly in paraview?

Many thanks,

Thomas

I’m afraid not, you will need to bake this in your data somehow.
