Dear Dr. Meng,

thank you very much for the detailed email with the valuable advice. I 
will give AutoPack a try.

Best wishes,

I would need a way to surround this molecule with a certain number of layers of solvent molecules that fit around the surface of a cylinder (preferably 1 layer and then going up gradually). The solvent molecules should be packed around the central molecule efficiently (closest packing). An alternative way to approach this would be to take a sphere made out of solvent molecules, put in the centre of the sphere the one cylindrical molecule what is of interest, and let the big sphere accommodate the new molecule. Also, for the sake of simplicity, the solvent molecules can be approximated as small spheres as well (their exact shape is not that relevant).
