Abstract

The heat transfer phenomenon is modeled by the Finite Difference Method (FDM) and the Soothed Particle Hydrodynamic (SPH) approach. The numerical approach under investigation may be used to solve many complex problems of applied mechanics. The Finite Element Method (FEM) is generally used for the Lagrangian description, and the FDM is used for the Eulerian report. However, the SPH method, which is better than other approaches to solve some problems, may be used in many aspects. Numerical details on the SPH method are discussed in this paper, with a focus on its application on the heat equation. A simple two-dimensional heat conduction problem is simulated by using the SPH approximation procedure and the newly constructed quartic smoothing function. Besides, a comparison is made between both techniques. Finally, C++ code is proposed for SPH and FDM methods.
