User defined failure criteria in abaqus

I am an Aerospace Engineer working at Advanced Composite Division of National Aerospace Laboratory, Bangalore.

I use Abaqus for stress analysis of composite structures.

Abaqus has five inbuilt failure
criteria for composite materials(Tsai-Hill, Tsai-WU etc.) whose contour
plots are shown by requesting output of a field variable called
CFAILURE.

I would like to know if it is
possible to request a contour plot of  a user-defined failure criteria
(which is not inbuilt in abaqus).

Is there a way that I can
input/type in the expression for a user-defined failure criteria in
abaqus GUI? And request its output like any other field variable so that
I can make contour plots of that Failure Index to locate hot spots in
the composite structure.

Thank you.
