Dear all,
I am doing a compression test of soil particles and want to divide the sample into 3 parts with the same volume along the z direction. During the compression, the shape of the soil assembly will be compacted and thus the subdomain region also needs to be redivided. I don't know how to model such deformable regions so as to adapt the subdomain every step? Could anyone give me any clues? Thanks very much.
Cheers,
Rachel
