SERIAL BOX SHOT 3D 3.6 SERIAL NUMBER GENERATOR

SeismicMesh's mesh generator is sensitive to poor geometry definitions and thus you should probably check it prior to complex expensive meshing. Points, cells = sliver_removal( points = points, domain = cuboid, edge_length = 0.10, preserve = True) Points, cells = generate_mesh( domain = cuboid, edge_length = 0.10, max_iter = 200) # Geometric primitives can be translated (while being rotated and stretched) import meshio from SeismicMesh import * cuboid = Cube( # Write to gmsh22 format with boundary conditions for the walls and disk/circle. ] # y=0.0 or y=1.0 cells_prune = cellsĬircle = sm. # We use the midpoint of the edge to determine its boundary label mdpt = points. # This gets the edges of the mesh in a winding order (clockwise or counterclockwise). Import numpy as np import meshio import SeismicMesh as sm bbox = ( 0.0, 10.0, 0.0, 1.0)

The user can still specify their own signed distance functions and sizing functions to generate_mesh (in serial or parallel) just like the original DistMesh algorithm but now with quality bounds in 3D. # NOTE: SeismicMesh outputs assumes the domain is (z,x,y) so for visualization # in ParaView, we swap the axes so it appears as in the (x,y,z) plane. # Meshes can be written quickly to disk using meshio and visualized with ParaView:: if comm.

SeismicMesh is distributed under the GP元 license and more details can be found in our short paper. SeismicMesh can also produce mesh-density functions from seismological data to be used in the mesh generator. For increased efficiency, the core package is written in C++, works in parallel, and uses the Computational Geometry Algorithms Library.

As an implementation of DistMesh, it produces high-geometric quality meshes at the expense of speed. SeismicMesh is a Python package for simplex mesh generation in two or three dimensions. SeismicMesh: Triangular Mesh generation in Python
