Finally, detailed comparative discussion is presented on the differences between the results obtained by FDM and FEM.doi:10.1080/10407789308902616Chen, S. C.Vafai, K.Taylor & Francis GroupNumerical Heat Transfer Applications
The continuum analysis methods, which idealise the material as a continuum, mainly include Finite Element Method (FEM), Finite Element Limit Analysis (FELA), Finite Difference Method (FDM), Macroelement Method, Discontinuity layout optimisation (DLO), and Material Point Method (MPM). Among different...

A uniform-grid FDM can provide these frequency/propagation constant differences between resonant/guided modes of coupled cavities/waveguides accurately with a coarse grid because absolute errors are common-moded out, whereas irregular meshes used in a FEM can introduce ‘grid induced’ or numerical ...

These displayed resistivity anomalies related to the cap rock and geothermal reservoir in the area. However, there are several significant differences in the model details, particularly between the FEMTIC and WSINV3DMT inversions. Numerical experiments on 3D synthetic data based on the inversion ...
Results are computed by a finite difference method (FDM) using the differential form of the constitutive equation, and by a finite element method (FEM) using the integral form. Even on fine grids, the two methods produce different results, particularly at low D e . However, extrapolation of ...
The Complex-Step-Finite-Difference method (CSFDM) is a very simple methodology that can be implemented in well known numerical techniques helping to improve, for instance in the wave propagation problem, time and/or space derivative based wavefields. We clarify differences between the CSFDM and ...
