![]() ![]() In many problems, that happens to be accurate. Both solvers, theoretically speaking, MUST give the EXACT SAME results. On the other hand, SPH is a better tool to use when fluid-solid interaction is of interest.Ībaqus employs either an implicit method (Abaqus/Standard) or an explicit method (Abaqus/Explicit) to solve the physics (i.e., differential equation converted into a discretized form). In the case of DEM, it's the particle-particle interaction that one cares more about. On the other hand, SPH/DEM fall under the broad category of the so-called meshless methods the documentation is pretty good at suggesting when to use these methods. ![]() That being said, here are my two cents:ĭepending on the amount of deformation a given physical phenomenon undergoes, within Abaqus, one may choose anything in between a purely Lagrangian analysis or a purely Eulerian analysis or something in between (Arbitrary Lagrangian-Eulerian with adaptive meshing or Coupled Eulerian-Lagrangian). However, the documentation is an excellent resource to get a few quick answers. That is a lot of questions! :) To be honest, these are advanced questions and, in order to capture the meaning, you will have to cross a threshold first - which is fun because there is so much more to learn. ![]()
