Radially oriented elongated grains

[avtarsinghh1991]

Hello NEPER Experts

I am new to neper. I am wondering if I can able to generate the grains with specific orientation given to individual grains along with the given average aspect ratio as shown in figure. Please help.

I am referring to the anisotropic Voronoi tessellation in which aspect ration and orientation of individual Voronoi cell can be defined.

I found the following command. Is it useful to do that?

oriaverage: set the cell orientations (field **cell/ori) as the averages of the cell voxel orientations (field **oridata).

Thanks in advance.

Best

If you mean radially oriented grains, it can be obtained using a circular seed distribution. You'd have to define it yourself (outside Neper), write to a file, and load the seed distribution using -morphooptiini coo:file(...).

If you mean grains with high elongation ratios and random distributions, Neper does not really allows it yet.
