# Calculation of electrostatics

Now we will have a look at the peptides electrostatics. To do so, highlight the System again and open the FDPB options dialog via the menu entry Tools ⇒ FDPB Electrostatics.

In the dialog all kind of settings can be done, but for now we take the Defaults and press OK.

The result is a (so far unvisualized) three dimenisonal grid around the molecule with its electrostatics, which is now added to the Datasets list.
