random small pores in polycrystal

[damulaoshi]

Dear Romain,
First, thank you so much for sharing this useful open-source package Neper with us.

I've seen the issue #339, but I'm wondering if it is possible to generate the random pores in the grains. The code that you've shown is based on a bimodal grain case; as such, the pores are always at the boundaries of grains. Is it possible to generate random small pores which distributed randomly in the polycrystal (which means, maybe these pores are located in the grains, maybe at the grain boundaries, maybe both)?

I've tested this:
neper -T -dim 3 -n 1000 -domain "cube(10,10,10)" -morpho gg -transform "rmcell(((x-3)^2+(y-4)^2+(z-6)^2) < (1.0)^2, ((x-7)^2+(y-6)^2+(z-3)^2) < (1.2)^2)" -o test

But apparently, I got "Abadon (core dumped)". Can you please give me some help with this sample generation?
Thank you before and have a nice day.

Best regards,
Damu

No, it's not possible. In this case, the best you can do is remove elements to generate pores.

Ok, as I thought, this is the only way. Thank you so much!
