TROPF (Tidal Response Of Planetary Fluids) enables efficient terrestrial fluid tidal studies across a wide range of parameter space. The software includes several different solutions to the governing equations in classical tidal theory, and can calculate millions of such solutions on several-minute-long timescales. Written in MATLAB/Octave, TROPF can be ported to Python and other languages, as the instructions for building the operator matrices are described in detail and the coding of core TROPF routines adheres to generic sparse matrix operations and avoids functions specific to MATLAB.
