[Gate-users] Problem with custom physic lists in Gate v7.1

[David Sarrut]

Hello,

this is the correct way to do: since the introduction of the PhysicList,
manually setting the physics is unstable and not recommended.
Recommendations are:
- 1) use the provided G4 physic lists, see the list here :
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Setting_up_the_physics#New_physics_list_mechanism
- 2) if PL are not enough for your needs, create your own (copied/inspired
from the ones in G4) like described by Andreas.

Andreas: if you think it can be useful to other people and if you want to
share your new Physic List in Gate, do not hesitate to send us your code
(ideally by a pull request on github ; contact me if questions).

thanks,
David
