Christoph Kords 6e64b5c476 better not allow for deads to contribute to flux, since not clear at which interface they got stuck 2013-05-07 18:47:17 +00:00
Christoph Kords 1c2c9b8436 ip neighborhood was screwed up for spectral solver as of rev 2332 due to new "mesh_spectral_ipNeighborhood": used to have fastest index in z direction although it should be in x direction!
also removed output of node twins in "mesh_tell_statistics" when using spectral solver, since not allocated
2013-05-07 17:50:58 +00:00
Christoph Kords fb5f94812f corrected format strings in mesh_read_meshfile and mesh_write_meshfile 2013-05-07 13:27:51 +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
2013-05-07 13:06:29 +00:00
Franz Roters d2416abdb4 introduced new keyword 'rotation' to specify texture rotation

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
2013-04-28 20:56:17 +00:00

Christoph Kords ca99274a5d fluxes now always periodic for spectral solver, no need to explicitly state this in the geom file by use of "periodic" keyword 2013-04-22 08:32:51 +00:00
Christoph Kords 60fa91be9a 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

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.
