Unable to use Stream tracer with custom source filter

Dear Support members,

I am trying to plot 3D magnetic field lines on the unstructured grid (data from the AMR model) but the Stream tracer with custom source filter is not working. First, I converted the cell data to point data type and then followed the relevant steps. For reference, you can see the LIC method is working perfectly for the data cube (attached png).

It would be really helpful if you could look at the issue. Here is the Google Drive link to download the data and the state file. Thank you for your time.

Somehown the streamtracer doesnt like Voxels for some reason. Using a tetrahedralize before the streamtracer fixes the issue:

Hi Mathieu,

Thank you so much for the prompt reply. With the tetrahedralize filter, I am able to visualise 3D magnetic field lines.

Thanks & regards,
Sahel
