Creating 3D Semi-Structured Grids Using Extrusion
Creating 3D Semi-Structured Grids Using Extrusion
When generating grids and meshes for fully three-dimensional structures with constant cross section in one or more directions, it is often advantageous to first create a two dimensional grid and extrude it to 3D, rather than generate a full 3D grid directly. By using the extrusion technique more control over the grid …
Creating Structured Grids Using FEATool MATLAB Functions
Creating Structured Grids Using FEATool MATLAB Functions
FEATool includes and per default uses the distmesh grid generation routines to automatically generate simplical triangular or tetrahedral grids for implicit geometries. However, the computational finite element library in FEATool also supports FEM shape functions for structured grids (quadrilaterals in 2D and hexahedra …
