julient31 bf5b3f96e9 Implemetation of SeqNei Algo 1
Still Seq and SeqNei versions
Loop on Neigh in SeqNei not working yet
2018-04-26 13:08:54 -06:00
julient31 4d375e72f0 Changes: - DMI and ME interactions
- Computation optimisations
         - lot of removed prints

Next work: - Sequential algo implemetation
           - temperature simulations (check)
           - Work on parallelization

julient31 7cc59fbbbe Same commit, beginning removing prints/checks and pushing 2018-04-26 13:08:54 -06:00
julient31 d53def5853 Field compute error apparently corrected. The issue was related to the reverse communication.
To do:
- Remove all checks/prints used to debug
- Check all the flag set in the atom_vec_spin creator (very important for the reverse comm)
- Code DMI/ME interactions
- Start to work on parallel implementation of the integration

julient31 af45d55b3f Added:
- For Paramag. simulations, the option "atom_modify" has to be set
ex: atom_modify sort 1000 4.0 (Freq,Dist).
- Actual time is now printed (c_mag[0] in compute_spin)
- Value of Gilbert's damping corrected
- Now even results for SD/Lammps comp. in purely paramg. or aniso. situations
- Pack and unpack reverse needed corrections (f only was set, not fm)
- Spin temperature is now computed (data c_mag[7] in spin_compute)

To do:
- Fcc with p p p bc is still not working
- If Zeeman/Aniso force not defined, error => to be removed
- Add DMI and ME (see if new file or add in the exchange file)

julient31 3168704858 For paramagnetic simulation (no pair interaction declared), the "atom_modify" command has to be used (in order to initialize the bin).
example: atom_modify sort 1000 4.0 (Freq. of sorting, Cutoff distance)

In order to print the actual time with the total mag., the vector associated to the mag. compute was modified. It is now: [time, Mx, My, Mz, |M|, En_mag]

Optimization of the spin_compute routine: energy and mag. have been gathered in a same loop.

julient31 9b0f8a0c55 First commit for the SPIN package.
Changes to come:
-Exchange interaction computation to check (loop on neighbors),
-Temperature/random fluctuations to correct (effects too strong),
-Physical results to check,
-Add final interactions (DMI, ME, Dipolar),
-Compute spin temperature (Nurdin and Ma formslisms),
-Work on MPI parallelization,
-Ewald sums to implement (see with Stan's pakage),
-See for prefered magnetic axis (Mitchell's idea),
