Paper Abstract

The paper studied error of the finite element numerical values, which was about the large-aperture optical components. Then, a one-dimensional model of beam and a two-dimensional model of square plant had been established, respectively. It calculated the two solutions of FEA and elastic theory in the different unit size. According to the results, it's found that the value of FEA was bigger than the theoretical solution, and the error of the finite element numerical values decreased with the increase of the number of units.
