Issue in making same microstructructure with different numer of elements.

Hi, I think you can generate the desired microstructure for your mesh convergence study in the following steps:

1. Generate a refined microstructure as you have done in your first image. Write the files necessary for your simulations and be sure to also write a .dream3d file for this microstructure.
2. Make a new pipeline where you read in the refined microstructure .dream3d file and use the "Change Resolution" filter to "coarsen" the microstructure. For example, if your original microstructure had a resolution (i.e., voxel size) of 1 and you changed this to 2 using this filter, this would be the same as moving from Case A2 to Case A1 in the image you showed below.

The problem with using your own features in the "Pack Primary Phase" filter is that you need to supply not just the grain center of mass but other metrics of the grain shape, and this will not generate the exact microstructure, since the grains are tessellated from scratch.

I hope that helps!

Best regards,
Kris
