  We present an online, open and comprehensive template library of
gravitational waveforms produced during the tidal disruptions of stars by
massive black holes, spanning a broad space of parameters. We build this
library thanks to a new feature that we implement in the general relativistic
version of PHANTOM, a smoothed particle hydrodynamics code for three
dimensional simulations in general relativity. We first perform a series of
numerical tests to show that the gravitational wave (GW) signal obtained is in
excellent agreement with the one expected from theory. This benchmark is done
for well studied scenarios (such as binary stellar systems). We then apply our
code to calculate the GW signals from tidal disruption events (TDEs), finding
that our results are consistent with the theoretical estimates obtained in
previous studies for selected parameters. We illustrate interesting results
from the catalogue, where we stress how the gravitational signal is affected by
variations of some parameters (like black hole spin, stellar orbital
eccentricity and inclination). The full catalogue is available online. It is
intended to be a living catalogue.
