New question #628632 on Yade:
https://answers.launchpad.net/yade/+question/628632

HI,

I created a complex structure in a CAD code and exported it as *.gts. In YADE, I filled this *.gts using cohfrictmat model and randomdensepack. But to my disappointment, the porosity of this packing is greater than 0.7. 

Actually, I want to model breakage of this brittle material whose porosity is no greater than 0.3. Besides, I also tried regularHexa, but this approach also got a lower solid fraction.

Recently, I checked the following questions: https://answers.launchpad.net/yade/+question/473518 and https://answers.launchpad.net/yade/+question/625502, in those questions, triaxial compression was recommanded to get a desired porosity, but ,in my simulations, a irregular boundary was used, triaxial compression also works on irregular packing??

Besides, I tried filterSpherePack function proposed in https://answers.launchpad.net/yade/+question/246971, but after the generation of a compressed cubic packing, I failed filter my irregular packing from the cubic packing and exported my packing. 

https://answers.launchpad.net/yade/+question/625502 shares a very similar problem with me, but this question has not be solved  yet.

Thanks in advance,

Tina
