How do you output simulation data to a hdf5 file?

Eric Stamper

Given any number of different dpf fields of data (for the same time and mesh scoping), how do you create one hdf5 file that contains all this combined information?

Answer, with help from Ayush:

def create_h5_file(path, *args):
    """
    Create a .h5 file to the given path from the data provided (DPF field/Fileds Container)
    """
    try:
        hdf5_op = dpf.operators.serialization.serialize_to_hdf5() # operator instantiation
        hdf5_op.inputs.file_path.connect(path)

        for i, data in enumerate(args):
            hdf5_op.connect(i + 3, data)

        hdf5_op.inputs.export_floats.connect(False)  # maintain double precision
        hdf5_op.run()
        return True
    except Exception as e:
        return False

# Define 3 differents sets of data to combine into 1 hdf5 file.
disp_op = dpf.operators.result.displacement()
disp_op.inputs.data_sources.connect(data_sources)
disp_op.inputs.mesh_scoping.connect(mesh_scoping)
disp_op.inputs.time_scoping.connect(time_scoping)
nd_disps = disp_op.outputs.fields_container.get_data()

node_coords_op = dpf.operators.mesh.node_coordinates()
node_coords_op.inputs.mesh.connect(mesh_from_scoping)
nd_coords=node_coords_op.outputs.coordinates_as_field.get_data()

tfs_op = dpf.operators.metadata.time_freq_provider()
tfs_op.inputs.data_sources.connect(data_sources)
tfs = tfs_op.outputs.time_freq_support.get_data()

# Write all fields into one .h5 file
out_path = r"D:\working_dir\combined.h5"
create_h5_file(out_path, nd_disps, nd_coords, tfs)
