Implementation of p-p Interactions in Molecular Dynamics Simulation

Submitted by Azadeh Sheidaei on

Dear All,

I want to simulate polymer system that have pi-pi interaction between


chains and reinforcements. I know there is no implemention of pi-pi


interaction in lammps.


So, Is there another method to consider pi-pi interaction in lammps? or


I can't simulate these system by lammps.




Regards,


Azadeh

FEAP - history variables for Elements

Submitted by Mubeen on

Hi all,

my question is about the history data storage in FEAP.

I am writing element subroutine (elmt01) in FEAP 8.3  for a history dependent problem.

I have written the stiffness matrix subroutine (stiff01), but it needs the data from the previous solution steps (previous strains, stresses, plastic strains, dislocation densities .... nh1,nh2=30 per point).

Scanning Valves Efficiently And Precisely Is Often A Nightmare

PROFILOMETER

Traditional ways of valve inspection using a contact profilometer are making way for the more recent non contact valve inspection technologies. Even though many of the specs of surface roughness globally are set as per the findings by a contact profilometer the ease of non-contact inspection systems plus the speedier technique of employing the high tech valve inspection technologies are definitely behind why significantly more professionals are purchasing the newest non-contact profilometer.

Great things about a customized valve inspection set-up
