[ESPResSo-devel] Two new particle properties

[Evyatar Arad]

Hi again,
As a part of implementing the aforementioned new integrator, I’ve come across 
the need to set two new particle properties. a_p and b_p. The two are constant 
throughout the simulation and are dependant on a particles mass and the 
Langevin friction coefficient.
I’ve added the two new fields under the ParticleProperties struct in 
particle_data.hpp.

1) In the comments it states that these should be properties which are not 
supposed to change during the integration (check), but have to be known for all 
ghosts. I’m no sure about the latter part of the statement…

2) Where do you think would be a good place to assign a value to these two? 
I’ve initialised the two values to zero at the beginning of init_particle.

A lovely Tuesday afternoon to all of you,
Evyatar.
