2.3.3.3.121. NXmicrostructure_imm_results

Status:

application definition (contribution), extends NXobject

Description:

Application definition for the results of the legacy (micro)structure generator ...

Application definition for the results of the legacy (micro)structure generator developed by the Institut für Metallkunde und Metallphysik at RWTH Aachen University.

The tool can be used to instantiate specific configurations for two- and three-dimensional discretized microstructures. Specifically, single-phase material that is composed of crystals, so-called (parent) grains which are tessellated into so-called sub-grains. Grains are modelled as elongated crystals to mimic fundamental geometrical constraints of the interface network in deformed material.

Symbols:

n_edge: Number of material points along the edge of the square- or cube-shaped domain.

c: Number of crystals.
