Number of grains in an RVE

Also just a follow up, DREAM.3D versions 6.5.x will also set features that are in contact with ANY feature id = 0 to a “surface feature”. So if you have a pore inside your structure with a feature ID = 0 then _any_ grain that contacts that pore will also be labeled as a “Surface feature”. This has become an option in DREAM3D version 6.6 and the nightly builds.

Hi Rishabh,
The "SurfaceFeature" will return 1 for grains that are in contact with the surface and 0 for grains that are subsurface (i.e., no cells exposed to the free surface). One way you can visualize this is using the attached pipeline (generated in DREAM.3D version 6.5.141). I used the "Single cubic phase equiaxed" prebuilt pipeline and then added the filters "Create Element Array from Feature Array" (to "copy" the information from each grain to each CELL of the grain) and the "Vtk Rectilinear Grid Exporter" (so you can open the .vtk file in ParaView). After you open the .vtk file, you can use the "threshold" feature in ParaView on the new "Surface_features_Element" cell data.
Best regards,
Kris

Kris,
Thank you so much for your response! That filter helped a lot. I just have another follow-up question. The exported .csv file has an attribute called "SurfaceFeature" that returns 1/0 for the corresponding feature id. I was wondering which output corresponds to the feature being completely embedded in the microstructure, whether it is 0 or 1.
Thanks
Rishabh

Hey Rishabh Sharma,
First, I assume you used the "SmallIN100 Full reconstruction" prebuilt pipeline as a reference for EBSD + serial sectioning in DREAM.3D? You'll need to tweak filter parameters but this should be useful to compute various statistics. The easiest way to count total grains and export statistics is to use the "Export Feature Data as CSV File." You can append this to the end of your DREAM.3D pipeline. The CSV file contains a row for each grain detected and whatever feature data you computed for each grain. Hope this helps!
Best regards,
Kris

Hello
I collected the data for an RVE via serial sectioning and EBSD scans of an Aluminum alloy. I assembled the data in Dream.3D into an RVE. I am an amateur and still learning the full potential of the software. I want to check how many grains I have in my RVE. I cannot find a filter that would extract/calculate that statistics from my data. Does anyone know of a way to count total number of grains from the RVE? That would really help.
Thank you
Rishabh Sharma

Hey Mike,
Just to follow up, which filter controls this option?
Best regards,
Kris
