You can partition selected cells by extending another face until it cuts through the selected cells. Extending a face is analogous to creating an infinite plane that is coincident with the face. ABAQUS/CAE creates a partition wherever this infinite plane slices the cells that you are partitioning, as shown in the following figure:
To partition cells using the extended geometry 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 datum plane method to partition cells using the 
tool, located with the partition cell 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 Cell.
The Method list displays the methods that you can use to partition a cell.
From the list of methods, select Extend face and click Apply.
If the part or assembly contains more than one cell, select the cells to partition. You can use a combination of drag select, [Shift]+Click, and [Ctrl]+Click to select more than one cell to partition.
Tip:
If you are unable to select the desired cells, 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.
ABAQUS/CAE highlights the selected cell.
Select the face that will be extended to create the desired partition.
