Dear Avogadro Forum,
My name is Alejandro Heredia Barbero and I try to measure the effect
of an electric field in organic molecules. Im new in Avogadro and I
want to use it for my research in biophysics and nanotechnology. Im
biologist and I would like to publish results obtained with Avogadro
in scientific papers so, it would be great if you can help me with
this. Additionally to this, I would like to do an insight in stability
of molecules when are in polymorphs. Your help would be very important
for my professional activities.

I'm not quite sure what you mean here. There are many possible effects of an electric field on an organic molecule -- not the least of which is a change in the electron density due to polarizability (and non-linear effects).
Most of these effects are best treated with various quantum chemistry packages, like MOPAC or Gaussian. (Although not all quantum packages can treat electric fields.)
This is one area of my research, so if you can be a bit more specific, I'm sure we can help you.

Again, I'm not sure I completely understand what you wish to learn. Do you wish to find different polymorphs for a given compound? Or do you have different polymorph crystal structures and you wish to calculate which is the most stable form?
The latter is definitely easier, but also requires a quantum package, for example ABINIT or VASP.
Hope that helps,
