| Abstract: | The method is introduced.Multigri mothod is used during solving the dynamic equations,of which the several times iterative and gradual grid subdivision are used to simplify the calculation of FEM.Its case analysis Shows the multigrid method has the advantages of using flexibly,reducing operand,simplifying calculation and restraining noise.The introduction of multi-grid method provides a useful tool for the study of crustal movement and deformation. |
