Example

This example shows how to change the resolution of an existing field.

import numpy as np

filename = "density.dat"
fields = read_from_file(filename)
fk.write_to_VTK("field.vtk", fields)

field_new = fk.change_resolution(fields, (64,64))
fk.write_to_VTK("res_64.vtk", field_new)

field_new = fk.replicate_fields(fields, (2,4))
fk.write_to_VTK("res_2_4.vtk", field_new)

Output

The following example outputs three 2D VTK files - field with resolution of (32,32), field with resolution of (64,64), and field with resolution of (2,4)
