Let me to introduce a program of molecular modeling "Abalone".
http://www.biomolecular-modeling.com/Abalone/index.htmlThe main features are:
- Molecular graphics
- Molecular model building
- Geometry optimization
- Molecular dynamics simulations
- Hybrid Monte Carlo
- Implicit and explicit water models
Much attention is paid to design the initial models. There is a constructor of chain molecules, which allows to create a model with pre-installed molecular-mechanical parameters form the residues. Users can create their own residues and add them to the database. There is a procedure for adding the box with a solvent, such as a water. This box should be made separately and then added to the model. The overlapping solvent molecules can be automatically removed.
