Hi,

I want to build an amorphous polymer (C-chain and H atoms) matrix using Amorphous Cell in material studio. First I sketched  a C-chain with H atoms. Then I use discover>> minimizer, after that, I added the C-chain to the amorphous cell, I set the target density is the density I want for the model and periodic boundary condition. It turned out some part of C-chain went out of the box ( specified a and b). What should I do to the atoms that out of the box? Should I just delete them? in that case, the atom number will be reduced. Or should I put them back to the box according to perildic boundary condition? and how I can know the bond length of C-C  and C-H?   I am new for material studio, and I hope someone can help me. Thanks very much
