Hi everey one
I want to pack molecules in concentric spheres region. The shell should contain one type of molecules, while the inner region should contain another type of molecules. The picture can help you understand what I want to do. I found some posts which can help me to pack molecules into spheres region (Updated Link​​​​​​​),
but it cannot help me to achieve what I want. How can I achieve my idea in MS?
Sincerely
Fan Li
