CCL: MM/MD program for Windows PC

 Sent to CCL by: "Anatoli  Korkin" [korkin^]
 I am looking for a free MM/MD program easy to install and operate in Windows PC
 environment to design some chemistry lessons for high school students, e.g.
 conformational changes and condensation/evaporation with temperature change.
 Even better if someone, who is expert in MM/MD, would be interested to join the
 project and develop some video lessons. See examples on my youtube channel
 "Atomic Scale Design for Newbies":
 Thank you for your advice and consideration!
