What is SPH particles in LS-DYNA?

Ashique Ellahi
28/04/2021 0 0

SPH( Smooth particle hydronyamics) is basically a meshless method where we have to fill a particular volume with zero dimensional elements.So you can import this iges cad file in Ls Dyna interface and fill this solid model with sph particles and then proceed further with the analysis.There are different options in the Dyna interface as to how much percentage volume you want to fill your solid model with sph particles. Then you have to give a kernel function radius etc for the sph particles. There are many you tube videos for doing this in Ls Prepost as well as HyperMesh.Please be aware that smooth particle hydrodynamics was first used to solve problems in astrophysics like the movement of celestial objects in space.
