WebA grain boundary is just a special case of a polycrystal where only two grains are constructed -each keyword "node" corresponds to one grain. The first grain is located at the position (0.5,0.25,0) and the second one at (0.5,0.75,0) as explained above. WebI am a structural geologist, and much of my recent works focused on investigating the crust's ductile and brittle deformation processes, from outcrop- to grain-scale. I use the EBSD technique and the open-source Matlab toolbox MTEX extensively for the latter. Although having worked in the Indian Himalaya for nearly seven years, laboratory analyses excite …
