WebGeneralized finite difference method The GFDM is evolved from the classical FDM with irregular grids, and its mathematical theories are the Taylor series expansion and the moving lest-square method. In the past 20 years, the GFDM has had many applications and numerically improved by researchers. WebIt is important to find an effective method to generate an accurate model and describe the multibody interaction mechanism of continuous-discontinuous system.
