Dear All
I want to build a triclinic solution box for with a fixed concentration. However, I only found three options in the Amorphous cell calculation -> construction task: tetragonal, cubic, and orthorhombic. I though about building a orthorhombic box then changing the angles of the box, but it will change the volume of the box and eventually change the concentration of the solution. Anyone has suggestions about that? 

Thank you very much.

Regards,
Jingjing
