2013-05-13 09:44:23 +00:00
Christoph Kords 6fac7c347c fixed bug in constitutive_nonlocal_kinetics that was introduced in rev2088 along with the non-Schmid behavior: nonSchmid matrix of last slip system was used for all slip systems; led to extremely bad convergence due to flawed dLp_dT 2013-05-10 22:29:12 +00:00

Christoph Kords c7f987a3c1 "unitlength" parameter, which determines the physical size of the mesh, now available as a global mesh variable "mesh_unitlength" and written to the .mesh file during init.
Hence, it is available to the marc_deformedGeometry.py script via "mesh_init_postprocessing()" and "mesh_get_unitlength()", so no need for setting the scaling of the displacement vectors explicitly through an option; now displacements and nodal positions are always consistent

Christoph Kords cc72c0b17b added two new scripts:
"marc_extractData" is a simple variant of the "postResult" script that extracts all data from a macro *.t16 file (quadratic elements not yet supported) and writes it into an asciitable
"addDataToGeometry" searches for corresponding *.txt and *.vtk file in a given directory and adds the data from the *.txt file as SCALARS to the *.vtk file

first script needed an additional function in mesh that returns the corresponding node of a given ip in a specific element

the meshfile that is needed for the init is created automatically by mesh_init in DAMASK

Christoph Kords 2a6ac44496 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.
