The development and use cases of an open-source filter for DREAM.3D that instantiates synthetic, grain-resolved, open-cell metal foam volumes are presented. The new capability allows for both synthetic-grain overlay of X-ray computed tomography data as well as fully synthetic foam geometry and grains. For the latter, a novel technique using Euclidean distances instantiates the 3D open-cell foam morphology, enabling user control of pore size, strut cross-section shape, and strut thickness variability. By integrating this approach into the DREAM.3D architecture, the entire DREAM.3D suite of filters is immediately available; thus, enabling both user control and quantification of grain size, shape, and crystallographic orientation statistics (among other metrics) as well as meshing algorithms to enable subsequent numerical analysis.

生成晶粒分辨开孔金属泡沫模型的工具

提出了DREAM.3D开源过滤器的开发和使用案例，该过滤器实例化了合成的，可分解颗粒的开孔金属泡沫体积。这项新功能既可以合成X射线计算机断层扫描数据的合成颗粒，也可以完全合成泡沫的几何形状和颗粒。对于后者，使用欧几里得距离的新技术可实例化3D开孔泡沫形态，从而使用户可以控制孔径，支杆横截面形状和支杆厚度可变性。通过将这种方法集成到DREAM.3D架构中，整个DREAM.3D过滤器套件立即可用。因此，既可以进行用户控制，也可以对晶粒尺寸，形状和晶体取向统计数据（以及其他度量标准）以及网格算法进行量化，以进行后续的数值分析。
