Mesh tools for professionals

Mesh tools for professionals.

MeshPro is a Python library and command-line tool for mesh I/O and mesh manipulation.

It supports all mesh formats supported by meshio.

Install MeshPro with

pip install meshpro

and retrieve a license key.

The full API documentation is here.

You can then use the command-line tool

meshpro convert    input.msh output.vtk   # convert between two formats

meshpro info       input.xdmf             # show some info about the mesh

meshpro compress   input.vtu              # compress the mesh file
meshpro decompress input.vtu              # decompress the mesh file

meshpro binary     input.msh              # convert to binary format
meshpro ascii      input.msh              # convert to ASCII format

or use MeshPro in Python with

import meshpro

MeshPro features

MeshPro meshes work exactly like meshio meshes, and they have a few extras:

import meshpro


# create mesh
mesh = meshpro.Mesh(
    [[0.0, 0.0], [1.0, 0.0], [1.0, 1.0], [0.0, 1.0]],
    [("triangle", [[0, 1, 2], [0, 2, 3]])],
)

# or read it in
# mesh = meshpro.read("mesh.vtk")

# remove duplicate points and take care of the indexing
mesh.deduplicate_points(tol=1.0e-10)

# remove all points which aren't referenced in any cell
mesh.remove_orphaned_points()

# remove a number of points or cells
# mesh.remove_points(mask)
# mesh.remove_cells(mask)

# add boundary cells
mesh.add_boundary_cells()

# add outer normals as cell data
mesh.add_outer_normals()

Other mesh manipulation tools are these:

import meshpro

# extract boudnary mesh
boundary_mesh = boundary_meshmeshpro.extract_boundary_mesh(mesh)

# merge some meshes
mesh = meshpro.merge_meshes([mesh1, mesh2, mesh3])

submesh = meshpro.extract_submesh(mesh, point_mask, cell_mask)

submeshes = meshpro.split_cell_sets(mesh, store_orig_node_ids_as="gid")
