The method and procedure for solving the problem of isokinetic contact elastohydrodynamics using multigrid technique are introduced. The iterative process of pressure is simplified in the algorithm; the elastic representation of the elastic matrix and the correction matrix in the elastic deformation calculation is proposed, which greatly reduces the amount of memory required by the program; in the range of 10-13≤U≤10-9,10- The range of 6≤W≤10-2 gives the stable region of the algorithm. By comparing with other solutions and empirical formulas, it is demonstrated that multi-grid technology will become one of the main numerical methods in the future study of the theory of the eruptive flow.
