pyLibMeshb

Python module to read/write mesh and solution files in Gamma Mesh Format (.mesh/.meshb/.sol/.solb). Implemented by compiling the vendored libMeshb source (libmeshb8.c / libmeshb8.h) directly and binding via Python ctypes.

Getting Started

Install

pip install pyLibMeshb

Read and write mesh data

Import pyLibMeshb

import pyLibMeshb.libMeshb as lm

Check mesh information.

lm.mesh_info("naca0012.meshb")

 File          : naca0012.meshb
 Version       : 2
 Dimension     : 2
 Type                     Kind             Count   Details
 ----------------------------------------------------------------------
 vertices                 vertex            4796
 edges                    element            192
 triangles                element           9400

Read a mesh.

mesh = lm.read("naca0012.meshb")

Mesh data is stored in a dictionary with keys for each data type.

print(mesh.keys())

dict_keys(['version', 'dim', 'vertices', 'edges', 'triangles'])

Write the mesh back out.

lm.write("roundtrip.meshb",mesh)

Verify consistency.

import numpy as np
check = lm.read("roundtrip.meshb", types=["vertices"])
print("Round-trip vertices match:", np.allclose(mesh["vertices"], check["vertices"]))

Round-trip vertices match: True

Read and write solution data

Solution demo: 3 synthetic scalar fields (e.g. density, pressure, Mach).

n = mesh["vertices"].shape[0]
demo_values = np.column_stack([
    np.linspace(1.0, 2.0, n),
    np.linspace(101325.0, 90000.0, n),
    np.linspace(0.1, 3.5, n),
])
lm.write("naca0012.solb", {"sol_at_vertices": {"values": demo_values}}, version=3, dim=2)

Check solution file information.

lm.mesh_info("naca0012.solb")

File          : naca0012.solb
Version       : 3
Dimension     : 2
Type                     Kind             Count   Details
----------------------------------------------------------------------
sol_at_vertices          solution          4796   sol_size=3, field_types=[1, 1, 1]

Solution data can be read using lm.read(). The mesh and solution can be visualized with Vizir4.

Query data types

Get lists of types in this mesh file.

mesh_types = lm.list_types("naca0012.meshb")
print(mesh_types)

['edges', 'triangles', 'vertices']

Get lists of types in this solution file.

solution_types =  lm.list_types("naca0012.solb")
print(solution_types)

['sol_at_vertices']

Get list of all types supported by pyLibMeshb.

all_types = lm.list_types()
print(all_types)

['corners', 'dsol_at_vertices', 'edges', 'hexahedra', 'isol_at_edges', 'isol_at_hexahedra', 'isol_at_prisms', 'isol_at_pyramids', 'isol_at_quadrilaterals', 'isol_at_tetrahedra', 'isol_at_triangles', 'isol_at_vertices', 'prisms', 'pyramids', 'quadrilaterals', 'ridges', 'sol_at_edges', 'sol_at_hexahedra', 'sol_at_prisms', 'sol_at_pyramids', 'sol_at_quadrilaterals', 'sol_at_tetrahedra', 'sol_at_triangles', 'sol_at_vertices', 'tetrahedra', 'triangles', 'vertices']

Testing

Install the package with its test dependencies and run the automated tests:

python -m pip install -e ".[test]"
python -m pytest
