Extrude a 2D mesh to 3D
This example shows how to extrude a 2D mesh to 3D. This can be helpful for
closed laboratory geometries for example. If you are looking for more flexible
ways to create 3D meshes, have a look at TetGen and Gmsh.
import numpy as np
import pygimli as pg
import pygimli.meshtools as mt
We start by generating a 2D mesh.
plc = mt.createCircle([-1, -4], radius=1.5, area=0.1, nSegments=25)
circle = mt.createMesh(plc)
for cell in circle.cells():
ax, cb = pg.show(circle, circle.cellMarkers(), label="Cell Markers")
We now extrude this mesh to 3D given a z vector.
z = np.geomspace(1, 5, 5)-1
cylinder = pg.meshtools.extrudeMesh(circle, a=z)
pl, _ = pg.show(cylinder, cylinder.cellMarkers(), label="Cell markers")
