Meshfree element method

Free element methodMeshfree methods are an alternative to the Lagrangian method in the finite element method (FEM), which allows models with very large deformations and material flows that can not be modeled using the Lagrangian method. , Be simulated. Fluid flow modeling, fluid-structure interaction (FSI), superplastic shaping, and grain material displacement are well-known examples in this field.


Abaqus software using three techniques in modeling the possibility of using non-network (Meshfree) are:

  • Smoothed Particle Hydrodynamics
  • Coupled Eulerian-Lagrangian
  • Discrete Element Modeling

The discrete element method (DEM) and the smooth particle hydrodynamics method (SPH) are both known as particle methods.


  • Using the SPH technique to model the extreme free surface currents of the fluid (such as shock wave) and the very large deformations of structures (such as shock ballistic)
  • The separate element method is used to model granular materials and perform analyzes such as mixing, separation, deposition, and transport of these materials.
    In the future, using this method in other software will be added to our services.
