"Grain radius" in grain input (v 6.402)
Posted: Fri Mar 06, 2020 3:28 am
Hi all,
The "(minumum/maximum) grain radius" in the random option of grain input seems a bit misleading.
For example, I would like to generate a structure of 5 round grains with a mean diamater of 80 μm (with periodic boundary conditions). I did a quick calculation and a box of 160x160 μm will be able to accommodate them theoretically. However, when I put in 40.00 for "min and max radius" though the structure will have "liquid" and the .TabK file gives an average radius of around 20 (based on area fraction). When I put in 80.00 for "min and max radius" then the structure is perfect and the average radius is what I want. An example input file (v 6.402) is attached.
I suspect that the term "grain radius" is misleading and the input values are actually taken as the diameters of the grains.
I wonder if this issue has been taken care of in 7.000, because from the document online it seems that the input file prompt is still "grain radius". I have did quite a bit of my work with version 6.402 so I'm a bit reluctant to migrate to 7.000.
Thanks,
Billy
