integration time in streamline datasheet

ParaView Support

When we generate some streamlines in paraview and export the spreadsheet out, one column is the Integration Time.
I want to know how I can control this? I may need to increase or decrease resolution of the streamlines and I assume the Integration Time would effect how many points are used to comprise streamlines, thus can change a streamline’s resolution.

Thanks

Change the value of the “Initial Step Length” in the advanced options of the streamtracer.

Thanks!
This might be tangential to my post topic, but still related to streamline generation.

I have a 2-D case from OpenFOAM and as you know 2-D cases in OpenFOAM are one cell thick in the third dimension.
When I generate streamlines from my inlet in paraView, I get two rows of streamlines lying on the back and front planes; however I only want one row of streamlines from the center of the cells.
I am not sure if I made myself clear or not. If not, please let me know so that I can provide more context.
Thanks

Ok, I found it.
First you need to apply a cell center filter to your inlet patch, then use the custom streamline filter to have your streamlines start from cell centers.
