Post Processing using Paraview

Hi,

I am trying to do some post processing using paraview. I converted .mrc files to vtk(ascii) using DPMICRESS.

But when I open them in Paraview, and do the necessary steps as in the post processing manual I only see one solid color. I do not see the segregation of elements. I have selected the coloring option to the data set.

When I try to re scale to visible data range, nothing happens.

What could be the reason here.

Hi Chamara,
In the Coloring option of Paraview, sometimes, by default, the 'Solid Color' option will be active. Change this to the field that you want to view (say 'conc1'). Then it should work.

Hej Deepu,

I did it. But it gives the colour associated to NaN.

But when I check the .vtk file it has correct values.

Hej Chamara,

are there any error message from the Paraview file reader?
Hard to say what is going wrong here. Can you attach the file or send it to support?
I tested Paraview 5.4.1 and DP_MICRESS VTK ascii output a minute ago. It works like a charm.

Hej Ralph,

I cannot attach it says file format is not support. I will email you.

Can you try to change the slicing pane to XZ ?
Seems that Paraview 5.5 takes XY per default, now. Former versions just evaluate dimensions as given in the VTK and present the 2D plane as defined.

Ah sorry!
I should have tried it with the same version before giving advice.
It works as expected at my site (win 64 bit, Paraview 5.5.0).

Maybe an OpenGL problem?
Can you try an installation on another machine?

Hej Ralph,

Could you put up a screen shot of the paraview with the results

It shows up from startup after applying the default settings.

Hej Ralph,

You were correct. It was OpenGL problem.

Worked on a different workstation level computer.
