stream tracer and structured meshes

Hi guys,
Jeff is having issues doing stream tracers on a large structured mesh. File format (that Jeff is writing) is .vtm. Is this a known bug, or are we doing something wrong?

nothing known. feel free to report issue with details.

The output of the stream tracer filter should be just polydata. Is he using group datasets or something like that to generate a composite dataset? I’m wondering why data is getting written out in a .vtm file?

Jeff will create a dataset that we can use to debug, and that I can send to Kitware. I will write up a bug when we can replicate. Thanks for the replies.
