How to build the welded zone in DREAM.3D?

[고태영taeyoung1516]

Hello All,

I'm trying to make a welded zone in RVE.

I'm making it with Dual Phase steel (so, it contains two primary phase with 0.62 and 0.38 fraction), and the total size is 60*60*60 (resolutions are fixed with 1,1,1)

I want to design welded zone in the center with 60*60*10 size, consequently, this RVE contains 60*60*25 coarse grain zone + 60*60*10 welded zone (fine grain) + 60*60*25 coarse grain zone. 

However, I cannot make it clearly because of the error, how can I solve this problem? 

I attached my .json file. 

Thanks!
