Is there a way to change the CollectionType
of the XDMF writer in Dolfinx? Currently the CollectionType
in the xdmf file is always Temporal
. I’m working on a project where I need to adjust the collection type but haven’t found clear documentation on this. Any guidance or examples would be greatly appreciated. Should this be done in post, or is there a way to solve this drectly with the writer?
import dolfinx
import numpy as np
from mpi4py import MPI
mesh = dolfinx.mesh.create_rectangle(MPI.COMM_WORLD, [np.array([-2, -2]), np.array([2, 2])],
[128, 128], dolfinx.mesh.CellType.triangle)
v = dolfinx.fem.FuncitionSpace(mesh, ("Lagrange", 1))
kappa = dolfinx.fem.Function(v)
out_file = dolfinx.io.XDMFFile(MPI.COMM_WORLD, "out.xdmf", "w", encoding=dolfinx.io.XDMFFile.Encoding.HDF5)
out_file.write_mesh(mesh)
for exponent in range(10):
kappa.interpolate(lambda x: x[0] ** exponent + x[1] ** exponent)
# Would like to encode the exponent in the collection type
out_file.write_function(kappa, exponent)
out_file.close()
