Interpolate field values at given points

Usage example

  1. Suppose you want to accurately determine the electric field at a set of positions. The electric fields are in a mesh called ernie_TDCS_1_scalar.msh

  2. Write the positions (x, y, z) where you want to sample the fields to a CSV file, as in this example

  3. Run

get_fields_at_coordinates -s positions.csv -m ernie_TDCS_1_scalar.msh

This will output one file CSV for each field in the mesh, named for example positions_E.csv, positions_magnE.csv, … These files contain the fields (or field vectors) at each sampling position.

  • Type get_fields_at_coordinates -h for more information and options
