You can create a mesh using C3D8R elements, write an input file, and then use a script to convert these elements to SPH particles.
WebNov 1, 2015 · The coupled SPH–FEM approach reduces high computational demand and the FEM meshes act as boundaries for SPH particles [23]. There are methods, such as tied contact, hybrid element coupling and nodes-to-surface contact, allowing the coupling interaction between SPH particles and FEM meshes. Webloading are shown in Figure 2 below. It can be seen that at the plane of symmetry, the applied displacement restraints are not violated. The identical results for a half …
