neper--相信做晶粒的大家都不陌生了,今天就再来介绍这块强大的linux下的voronoi建模软件。 网址:http://neper.sourceforge.net/
缺点:一款全新软件需要长时间学习;需要熟悉linux操作及命令;此软件使用人较少,缺少讨论对象
优点:除了缺点,嘿嘿
基本介绍:
[tr]Neper: polycrystal generation and meshing[tr]Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are: Generation of polycrystals from (experimental) morphological properties [tr]Standard approaches (regular tessellations and Voronoi or Laguerre tessellations) are also available.
- [tr]Grain size distribution, grain shape distribution, etc.
- [tr]Grain-by-grain data as obtained for example in synchrotron X-ray diffraction (3DXRD, DCT, HEDM, ...) and such as grain centroids/volumes or a full polycrystal image.
Generation of multiscale microstructures [tr]Each cell of a primary tessellation is partitioned into a new tessellation, and the process can be repeated an arbitrary number of times. This can be used to mode complex microstructures such as bainitic steel, lamellar Ti-6Al-4V, etc. Generation of periodic or semi-periodic microstructures [tr]The tessellations (and their meshes) can be prescribed periodic or semi-periodic conditions to cancel the effect of free surfaces or reduce the size of the RVE. NEW (version 3.3): Generation of uniform orientation distributions [tr]Orientations can be uniformly distributed (flat ODF) for any number of orientations and any crystal symmetry. Some orientations can even be prescribed. Meshing into good-quality elements [tr]Meshing involves specific methods called regularization, multimeshing and remeshing. The mesh size can be uniform or defined on a per-grain basis. Meshing with cohesive elements at interfaces Visualization and analysis of the tessellations and meshes [tr]The scene can be set in great detail and images are generated with publication-quality rendering (see the image on the right). Several metrics are available on the morphological and topological properties.
[tr]Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system. [tr]下面只放效果图了,详细的自己去官网看(包括软件下载): [tr] [tr]
