hi michael, Here are some questions I would like to ask you. When I tried to model using your pipline and corresponding STL files, the resulting model was shown below (including the Initialize Synthetic Volume model and the corresponding hole model), which is not the effect you showed (only the hole model with grains, in this conversation:
Generating random multi-crystal 2D plane with one hole at center. ). And the astmd638_stpaecimem in exmap also has the same problem after running. Looking forward to your explanation on how I can achieve the same effect as you. thank you..
The results you presented
