lattice: (re)introduced _symmetryType function to replace unsafe lookup array
...
numerics: polishing
mpie_cpfem_marc: polishing
..powerlaw: aware of symmetryType function
crystallite: aware of symmetryType function, smaller leapfrog acceleration
IO: new warning 101
CPFEM: range of odd stress is now -1e15...+1e15, H_sym is used for stiffness

* now able to choose method for state integration (integrator and integratorStiffness in numerics.config); standard is "Fixed Point Iteration", which is basically the same as before; others available are "Explicit Euler", "AdaptiveEuler", "Classical Runge-Kutta" and "Runge-Kutta Cash-Karp"
...
* now remembering stiffness similar to how we do it for Lp etc.; avoids undefined stiffness values for nonconverged stiffness calculation
* non-local stuff:
* changed non-local kinetics (Gilman2002)
* enforce zero shearrate for overall carrrier density below relevant density
* enforce zero density for those states that become negative and were below relevant density before
* dislocation velocity is not limited by V^(1/3) / dt anymore

Fixed a missing ','. Assigned plane and direction names.

1ae252c1ce
altered hexagonal slip systems
...
(needs comparison to former set, which is potentially wrong)
2010-09-30 17:31:19 +00:00
b259fbd9c6
1) added distribution of leapfrog breaks
...
2) lattice_symmetryType is now a function (former lookup array was buggy)
3) stricter check of state var values (>0!) and memory deallocation done
2010-09-30 07:31:53 +00:00
e4067f2d26
debugged zoo of rotation operations and transformations
...
all angles now in radians
introduced a rudimentary check in math_init to complain (IO_error) about broken transformations (e.g. quat --> R --> quat)

New output can be requested from crystallite:
...
(output) grainrotation
it gives the deviation from the initial grain orientation
in axis-angle representation with the angle in degrees.

allow for longer pathes when openening files
...
corrected error messages concerning file openening
2010-02-18 08:29:57 +00:00
5d5e7eb8f8
corrected uncritical mix-up of Ntwin and Nslip in reshaping fcc interaction (slip--twin)
2009-10-21 13:41:09 +00:00
4e98935287
changed lattice_interaction matrices to (other:me) notation
...
fixed small mistake in hexagonal twin--slip interaction matrix
adopted above switched notation for hardening matrix calculation
shortened dotState by introducing dot_product notation
2009-10-21 13:10:12 +00:00
e1586d5059
fixed (probably severe) bug in hexagonal twin system transformation into ortho-hexagonal coordinates.
...
cleaning up of twin system nomenclature
introduced lookup mechanism to calculate the twinning shears depending on the c/a ratio of the present structure (was [wrongly!!] hardcoded to Titanium)
2009-10-20 16:13:25 +00:00
974116808b
fixed a potential memory leak for hexagonal structures. added some status output to constitutive_xx

bb8a71557b
Added comment on FCC different interaction types
...
1 --> self
2 --> coplanar
3 --> collinear
4 --> Hirth locks
5 --> glissile junctions
6 --> Lomer locks

lattice.f90: correction of typo from the last update (Philip)
2009-08-26 09:02:22 +00:00
7720680f3a
makeMe: some polishment
...
lattice: found memory leak (lattice_interactionTwinSlip had wrong size) and added further commenting
2009-08-26 07:28:43 +00:00
9bbde133a1
Updated constitutive_dislobased.90 and lattice.f90 according to the changes done in the previous release
...
- introduction of system families
- analogous structure to constitutive_phenopowerlaw.f90
- interaction types 0-1 changed into 1-2
2009-07-24 12:02:20 +00:00
f337847f35
quite some changes:
...
# non-greedy memory allocation
# generation of outputConstitutive to allow for script-based T16 extraction
# exchange of phenomenological by more general phenopowerlaw
# lattice is based on slip and twin families which can be treated as individual entities (switched on/off, separate hardening, etc.)
# nicer debugging output
# changed some error/warning codes
# plus potentially some minor additional brushes here and there

Corrected definition of vector n and d per deformation system; n is the system plane normal and d the corresponding direction

restructured the repository: renamed trunk into code, moved documentation one directory up, therefore you can now checkout either code or documentation only if you like
