This presentation show the basic meshing techniques for abaqus users

1. Introduction (3/3) General capabilities of the Mesh module Allows you to mesh an assembly using various levels of automation and controls to suit the needs of your analysis Assign mesh attributes and set mesh controls to specify: Meshing technique Element shape Element type Mesh density Generate the mesh Query and verify the mesh for: Number of nodes and elements Element type Element quality Mass properties

2. Dependent and Independent Part Instances (1/4) Concept of a part instance A part instance is a representation of the part in the assembly A part instance can either remain dependent on the original part or be designated independent of the original part Independent instances can be partitioned at the assembly level. Multiple independent instances of a given part can be partitioned each according to its own requirements (mesh, loads, etc.) Each independent part instance must be meshed separately Dependent instances cannot be partitioned at the assembly level. All dependent instances of a given part share the same geometry as the original part. Thus, only the original part needs to be meshed Its dependent instances will inherit its mesh Any partitions must be made to the original part. Misc. For either dependent or independent instances: Different attributes (loads, boundary conditions, etc.) and sets/surfaces can be created. All instances of a part must be either dependent or independent. No mixture is allowed for a given part. All orphan mesh instances must be dependent.
