The error part.apparatus-material

user: the script can change it: the error says what happened in the experiment’s names, and what to write instead.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/build/_plan.py:

  • what happened: {…} lies inside another part, or names a material that is no record: an apparatus's part is a solid fixed to a frame, with its own density (its moment is declared, as {…}.magnetic_moment)

  • what to do: drop inside=; name a material as a mime.materials.Record, or declare the part's density or mass ({…}.parts.<part>.density)
