The system performance of high-precision optical systems is highly sensitive to transient mechanical and thermal disturbances. In order to precisely predict a systems operating performance these disturbances need to be modeled, simulated, and analyzed. In this work, a numerical method is presented which allows for the consideration of transient mechanical rigid body motions, mechanical and thermal elastic deformations, and thermally induced refraction index changes in the transient simulation of optical systems operated with lasers.
