已经开发了一种将有限元分析（FEA）结果传输到光学设计程序CODE V1的方法，尽管该方法可以容易地适应于支持Zernike表面的其他光学设计代码。这种方法在许多方面都比用于执行这种数据传输的商业代码中使用的方法有所改进。该方法假设表面节点位移纯粹是在位移节点的径向位置处的垂度（z轴）方向上。这消除了将变形作为伪干涉图传递时所需的近似，并且消除了在干涉图的光线跟踪中所做的近似。已包括特殊技术，以消除FEA程序中引入的不准确性。该方法已在一系列测试用例上得到验证。
A method for transfer of Finite Element Analysis (FEA) results to the optical design program CODE V1 has been developed, although the method can be readily adapted to other optical design codes that support Zernike surfaces. This method is an improvement in many ways over the methods used in commercial codes written to perform this data transfer. The method assumes the surface nodal displacements are purely in the direction of the sag (z-axis) at the radial location of the displaced node point. This eliminates the approximations necessary when transferring the deformations as pseudo-interferograms, and eliminates the approximations made in the ray tracing of interferograms. Special techniques have been included to remove the inaccuracies introduced in the FEA program. The method has been validated on a series of test cases.
