  The thermal experiments to be carried out onboard LISA Pathfinder (LPF) will
provide essential information of the dependences of the instrument with respect
to temperature variations. These thermal experiments must be modelled and
simulated both to be validated for mission operations purposes and also to
develop a data analysis tool able to characterise the temperature noise
contribution to the instrument performance. Here we will present the models
developed and the simulated signals for some of the experiments together with
the corresponding interferometer readouts, the latter being computed by
combining the thermal models with the global LTP (LISA Technology Package)
simulator of the LTP Data Analysis team.
