| Abstract: | The plane electrostatic field with pentagon boundary is studied in Cartesian coordinate system by using finite difference method.First,the definite solution problem satisfying pentagon boundary conditions,and corresponding algorithm are proposed.Second,the numerical solution of electrostatic field is obtained using finite difference method and Fortran program,and the diagram of electrostatic field distribution is drawn by using Origin software. |
