openmc2dolfinx
openmc2dolfinx is a lightweight tool for converting OpenMC output data (in .vtk format) into dolfinx-compatible fem.Function objects.
It is primarily designed to facilitate multiphysics coupling between OpenMC and finite element simulations (e.g. thermal, diffusion, or tritium transport analyses).
Key features
- Convert structured and unstructured VTK meshes to dolfinx meshes.
- Interpolate OpenMC tally results directly into dolfinx Function spaces.
- Integrated with PyVista for mesh and data inspection.
Installation
Using conda:
bash
conda create -n openmc2dolfinx-env
conda activate openmc2dolfinx-env
conda install -c conda-forge fenics-dolfinx=0.9.0 mpich pyvista
Once in the created in environment:
bash
python -m pip install openmc2dolfinx
Example usage
```python from openmc2dolfinx import StructuredGridReader, UnstructuredMeshReader import pyvista as pv import numpy as np import dolfinx from mpi4py import MPI
download an example tetmesh
filename = pv.examples.download_tetrahedron(load=False)
grid = pv.read(filename)
assign random cell data
grid.celldata["mean"] = np.arange(grid.ncells) grid.save("out.vtk")
read the vtk file
reader = UnstructuredMeshReader("out.vtk")
make a dolfinx function
u = reader.createdolfinxfunction("mean")
export to vtk for visualisation
writer = dolfinx.io.VTXWriter(MPI.COMM_WORLD, "out.bp", u, "BP5") writer.write(t=0) ```
