Hi Alex,
Chimera does not do MD, so I'm guessing you just want to use it to prepare the structure before doing MD with some other program.

You can add bonds with the Build Structure tool (Tools... Structure Editing... Build Structure, go to Add/Delete Bonds tab) or the command "bond," but first you have to combine the receptor and ligand into one model.  Chimera will not bond two different models.


You can combine the two models with the "combine" command, or by choosing the two models in the lefthand side of the Model Panel (opened from Favorites menu) and then clicking the "copy/combine..." button on the right.  That will open a GUI with more settings for generating the new combined model.


In the combined model, you can add the bond as mentioned above.

I hope this helps,
