Hi everybody,
I'm trying to create an Engine that aplly Electrostatic force to a sphere.
I´d like to allow displacement of bodies depending on the charge and  
the electrical potential.
Perhaps I should precise that I´m quiet new to Yade and C++ programmation.

To do so, I decided to inspire myself with an already written  
preprocesor: "funnel", which has been modified in order to generate a  
random cloud of spheres in a closed box.
At this step every thing is working as I want to.

* Creation of a new stand alone Engine:
As well as I did before, I used an already written engine and modified  
it. But here is the problem.
- I copy paste the GravityEngine.
- rename it, rename the functions within and shrd_ptr,
- I also rename the .hpp file
- add it in the corresponding scons file
It compiled well (no error) and was added to the libnewengine.so.

In esance it should do exactly the same thing than the GravityEngine  
but with a different name.

Nevertheless, when I try to use it within my new preprocessor, it  
doesn´t appear anymore in the preprocessor generator list (yade  
graphique interface).

Moreover, If I just declare it in the list of classes used withtout  
using it (like declaring something that you don´t use), the  
preprocessor also don´t appear in the preprocessor list...
Is anybody has any idea about what is wrong.
Thanks for your help,
Best,
Ben
