This chapter discusses features related to analysis techniques in Abaqus. It provides an overview of the following enhancements:

• “Finite element conversion to SPH particles based on a uniform background grid,” Section 5.1

• “Generating particles based on user specifications for DEM,” Section 5.2

• “Enhancements to particle interface behavior for DEM,” Section 5.3

• “User load for DEM,” Section 5.4

• “Improved boundary behavior based on ghost particle method,” Section 5.5

• “Skipping restart output altogether for Abaqus/Explicit analyses,” Section 5.6

• “Importing model data and results multiple times for Abaqus/Explicit analyses,” Section 5.7

• “Defining substructure damping and substructure modal damping,” Section 5.8

• “Redistributing the mass of an element set using a scale factor,” Section 5.9
