> ### Molecular Dynamics simulation

> A <it>Molecular Dynamics (MD) simulation</it> is very computational intense: 30 steps for a molecule like the currently loaded take around 20 seconds, depending on the computational power.
> When the simulation is over we will leave the field of molecular mechanics and come to an other field:
> To understand a protein's function, it is often also necessary to study its <it>electrostatic field</it>. This can be easily done using BALLView, where you can compute the electrostatic potentials in space in an FDPB setting with just a few mouse clicks.
> When you press Next, such an FDPB electrostatic computation will be performed. Depending on the performance of your machine this might take a moment.
