03d8f14a98
introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
...
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).
not specifying a density (density = 0) will perform a quasi static simulation as before.

Fixed bug in math rotations: passive and active rotations were not clearly distinguished and partly mixed up; yet, luckily, only resulted in wrong output of euler angles.
...
Now fixed with following convention:
Rotation conversions do not switch implicitly from active to passive or vice versa EXCEPT when converting to or from any "Euler" type (Euler angles or Euler axis/angles). Those functions expect a passive rotation as input if converting to Euler type and return a passive rotation if converting from Euler type.

calculation of cellnode positions now available in python via damask.core
...
first call damask.core.mesh.mesh_init_postprocessing(meshfilename) to initialize all necessary mesh variables
then damask.core.mesh.mesh_build_cellnodes(nodes) calculates the cellnode positions for a given list of node positions
the meshfile that is needed for the init is created automatically by mesh_init in DAMASK

Major restructuring of mesh.f90 due to introduction of "cells". A cell is the volume (area in 2D elements) that surrounds an ip. It is described by up to 8 cell nodes and is used to calculate ip volume, area, and face normals. It can also be used to generate a mesh for e.g. paraview that contains ip output as cell centered data.

restructured AL solver to resemble polarization scheme and introduced alpha and beta parameters in numerics to determine what kind of solution you want. alpha = beta = 1 results in the AL scheme. alpha = beta = 2 results in the accelerated scheme. safe values are anything in between. changed the solver to use stress calculations on the campatible field which seems to result in faster convergence.

...
first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.

switched saturation behavior!!
...
was \dot s_alpha = (1-s_alpha/s_inf)^a h_alphabeta \dot gamma_beta
now \dot s_alpha = h_alphabeta (1-s_beta/s_inf)^a \dot gamma_beta
current form is consistent with the genmat implementation (and appears to make more physical sense). Kalidindi_etal1992 suggested this form, but altered it to the alpha-one in Bachu+Kalidindi1998... By now, it seems that some groups use alpha, others beta approach.
introduced two new absolute tolerance values for "shears" and "twinFrac" (default 1e-6).

In crystallite for state integrators 2 and 3: now that "stateJump" is called before integrating dotState, we have to do state = state + dotState *dt instead of state = subState0 + dotState * dt; otherwise the deltaState is lost
2012-10-22 13:34:15 +00:00
0980920b66
In crystallite: for state integrators 2 and 3 the deltaState always has to be done at the beginning of the integration, not at the end; otherwise the stiffness calculation can be completely wrong, when the state is changed after the stress integration for the central solution.
...
Also changed some debugging levels in crystallite and mainly in constitutive_nonlocal

modified multiplication term in order to mimic a discrete distribution of dislocation sources; namely, at high resolution, when there is (on average) less than one source per integration point, a random generator decides whether there is a source in the finite volume or not; if there is one, then the multiplication turns independent of the density and depends only on the velocity/volume times a scalar factor; recovers density*velocity/lambda for large finite volumes

for state integrator 2 (explicit euler) and 3 (adaptive 2nd order euler): don't do any state evolution during stiffness perturbation, but only stress integration, since for those cases the state is not restored after every perturbation step
