[dmritool-discussion] Paraview help

[Nagesh Adluru]

Hi Jian,

Thank you for the tips about translation and scale. If you get time to make
consistent meshes compatible with paraview that would be nice but I do
understand you have a lot of things to do:)

I will do what I can with paraview or just use vtkviewer from your toolbox
for now!
Sincerely,
Nagesh
