Abaqus/CAE merges the end nodes of element edges that are shorter than the specified length. By default, Abaqus/CAE checks all element edges in a mesh part, but you can specify a different element domain. For structured meshes you can specify a thickness

Once you have selected the element type, you can design the mesh for the connecting lug. The most important decision regarding the mesh design for this example is how many elements to use around the circumference of the lug's hole. A possible mesh for

With the help of mesh module in Abaqus/CAE you can generate mesh in parts and assemblies.You can assign the mesh using different mesh characteristics such as element shape,element type and mesh density.you can also refine the mesh by seeding the mesh dens
