With my students we are emulating the propane conformation analysis, what is known topic in Organic Chemistry.
As we found, all given constraints in the list are active, therefore for each torsion angle one has to set up own constraint and delete the previous.
For smooth calculations we would welcome the possibility to create list of constraints and select(activate) some of them for calculations. This would enable us to prepare torsion angles constraints in advance and simply click on the constraint to activate it for the geometry optimization.
It would help at least if given constraints are editable.
Also, options save and load are not working… Would be good to have them working.
I think that the conformation analysis, as taught at Organic chemistry courses, is nice teaching example with Avogadro.
