I/O#

Conversion between PhysicsNeMo Mesh objects and PyVista meshes. Because PyVista supports a wide range of file formats (VTK, STL, PLY, OBJ, and many others), this module serves as the primary I/O gateway for PhysicsNeMo-Mesh.

from_pyvista()

Convert a pyvista.PolyData or pyvista.UnstructuredGrid to a Mesh. Point data and cell data arrays are carried over.

to_pyvista()

Convert a Mesh to a pyvista.PolyData (for surface meshes) or pyvista.UnstructuredGrid (for volume meshes).

import pyvista as pv
from physicsnemo.mesh.io import from_pyvista, to_pyvista

# Load any format PyVista supports
pv_mesh = pv.read("geometry.stl")
mesh = from_pyvista(pv_mesh)

# Work with the mesh in PhysicsNeMo...
mesh = mesh.subdivide(levels=1, filter="loop")

# Export back to PyVista for saving or visualization
pv_out = to_pyvista(mesh)
pv_out.save("refined.vtk")
