The photothermal and photoacoustical effects can be described by means of thermo elastic wave equations. However, analytical solutions describing those processes in optical components consisting of several optical coatings are not known. We have applied the Local Interaction Simulation Approach (LISA) in order to simulate the generation and propagation of thermoelastic waves in homogeneous and layered two dimensional media. A sharp interface model was applied at each layer interface. A few selected examples of thermoelastic wave propagation in two dimensions are presented.
