This Python 3 code orchestrates the volume meshing of a microstructure output from DREAM.3D<\/a>. The code simply reads in binary STLs output by DREAM.3D, calls gmsh to volume mesh them, stitches the individual volume meshes together into a single conformal mesh, and outputs an ABAQUS .inp file ready for processing in ABAQUS CAE or (with the help of translators<\/a>) other platforms. Please read the comments at the top of the code for usage instructions. The user need only modify three variables in the program: working_directory<\/em>, gmsh_executable<\/em>, and stl_prefix<\/em>.<\/p>\n\n\n\n Download Here<\/a><\/p>\n\n\n\n This Python 3 code reconstructs a virus into a geometric model. In essence, it processes a VIPER Database<\/a> (.vdb) file to capture the geometric features of the virion membrane. A grid-based description of the membrane is output into a .ph file for surface meshing in DREAM.3D<\/a>. In short, the code processes all atoms in a .vdb file, fits a three-dimensional grid around these atoms, and maps densities onto the grid points. The closer a grid point is to a cluster of atoms, the higher its density will be. Here, a grid point’s density is calculated using a Gaussian KDE. Based on a user-defined density threshold, grid points are categorized either as solid or vacuous space. This routine was inspired by the density-based reconstruction approach presented in this paper<\/a>. The user need only modify the variables working_directory<\/em>, vdb_file_name<\/em>, ph_file_name<\/em>, density_threshold<\/em>, and grid_resolution<\/em>.<\/p>\n\n\n\n Polycrystal Volume Mesher Download Here This Python 3 code orchestrates the volume meshing of a microstructure output from DREAM.3D.
