<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>It looks like your mesh comprises voxel elements instead of hexahedral elements. I guess voxel elements are not really well supported in unstructured grids (you are supposed to use hexahedra instead). How did you create this data set? Did you start with a structured grid and convert it to an unstructured grid?<BR>

<BR>
While all paraview features work perfectly fine for my<BR>
unstructured mesh output, I cannot get streamlines to show up (or they<BR>
are too small to see). This only happens on warped geometries -- if the<BR>
geometry is a Cartesian box, everything works.<BR>
I've tried the CleanToGrid feature to align nodes and avoid holes due to<BR>
roundoff in the mesh, but not had any success.<BR>
It must be some simple problem, for instance caused by not perfectly<BR>
aligned elements, but I do not see the problem. I'd highly appreciate<BR>
any hint.<BR>
<BR>
Here is a small test example where I have the problem (I use v3.4 but<BR>
have tried other versions as well)<BR>
