You can partition selected faces by extending another face so that it cuts through the selected faces. Extending a face is analogous to creating an infinite plane that is coincident with that face. ABAQUS/CAE creates a partition wherever this infinite plane slices the selected faces you are trying to partition, as shown in the following figure:
To partition faces using the extended face method:
From the main menu bar, select Tools
Partition.
The Create Partition dialog box appears. ABAQUS/CAE displays prompts in the prompt area to guide you through the procedure.
Tip:
You can also use the extended face method to partition faces using the 
tool, located with the partition face tools in the module toolbox. For a diagram of the partition tools in the toolbox, see “Using the Partition toolset,” Section 44.2.
From the Type radio buttons at the top of the dialog box, choose Face.
The Method list displays the methods that you can use to partition a face.
From the list of methods, select Extend another face and click Apply.
Select the faces to partition. You can use a combination of drag select, [Shift]+Click, [Ctrl]+Click, and the angle method to select more than one face to partition. For more information, see “Selecting objects within the current viewport,” Section 6.2.
Tip:
If you are unable to select the desired faces, you can change the selection behavior by clicking the selection options tool 
in the prompt area. For more information, see “Using the selection options,” Section 6.3.
