摘要
描述了非线性自适应有限元的多重网格法求解过程。
A procedure of multi grid solution to adaptive nonlinear FEM is described in this paper. Numerical analyses on underground cavern excavation have shown the effectiveness of the procedure and the advantages of adaptive multi grid FEM in the simulation of excavation process.
