FEM requires a discretization (a mesh or a model) of a domain.
FEM需要对域进行离散化(一个网格或者模型)。
The result shows that model is economic and credible in the discretization of far-field of infinite domain, especially to researching for dynamic problems.
结果表明，用这一模型来离散无限域的远场，特别是研究动力问题，具有较好的经济性和可靠性。
The discretization grid size of the inhomogeneous object domain was reduced gradually by using the multi-grid technique in the inversion procedure.
在反演过程中，采用多重网格技术将待反演区域的离散网格从粗网格逐渐推演到细网格。
