440d22bc99 * Changed the exit condition for a few external classes in case the xml-file is not found. 
Until now the program terminated with a segmentation fault which was not very user friendly...

* Got rid of a strange construction in the TRIM.SP handler (vector<pair> -> map)

c3316e9676 Fixed another problem (which I previously overlooked) in the implementation of EHB: PRB 71 014521 (2005) 
* In the limit of thick films the result now is consistent with EHB: PRL 78 2208 (1997)
* B_z at the vortex-core has the correct values as a function of depth
* The calculation needs time...

* Any review is welcome

7357caa8b8 Fixed the implementation of EHB: PRB 71 014521 (2005) 
* The iterations converge now!

* B_z at the vortex-core has the correct values - as far as I can judge on it using EHB's work

* However, B in general might still be wrong by some factor, esp. B_x and B_y at the surface.

* There are many things left for optimization - e.g. there are (dependent on the grid size) thousands
  to hundreds of thousands zero-assignments which could be removed after some careful checks

* Any review is welcome

620465fadc Changed some things in the implementation of EHB: PRB 71 014521 (2005) 
- Fixed an error in the calculation of the gradient of the order parameter
  This fixes the vortex-shape and the iterations behave a bit more converging
  (not really but definitely better than before)

- The fields still disagree with EHB's calculation

2aaa56959c Changed some things in the implementation of EHB: PRB 71 014521 (2005) 
- 3D iterations now keep the hexagonal symmetry (the irritating compiler warning was right after all...)

However:

- Iterations do not converge at all...
- The maximum of the field is slightly off the vortex core ;-(
- This problem is cursed!

c663446dae Added a masochistic try to implement EHB's work: PRB 71 014521 (2005) 
It is not working at all in the current state and therefore also not included in the library.

- 2D calculation seems okay - at least the symmetry of the hexagonal lattice is kept through the iterations
- 3D iterations destroy this symmetry... I guess it is only a small problem, however I do not see it right now
- EHB's matlab code is available - however, it treats the problem quite differently

In case this is ever going to work, some things could probably be more optimal:
- Replace the numeric gradient calculation by the "analytical gradient"
- Use only every second Fourier coefficient in K-space and keep the number of points
  This should reduce the factor of redundancy in real space from 8 to 2 and increase the spacial resolution by a factor of 4!

723cd29dcd Changed the Makefile of libTFitPofB for more general use. IGNORE TBulkVortexFieldCalc.cpp for the moment. It's a toy for small children which is not working at all at the moment. Furthermore, IGNORE all pragma-warnings during compilation. 2009-11-14 09:39:31 +00:00
