U(1)

Total value of the prescribed variable at this point. The variable may be displacement, rotation, pore pressure, temperature, etc., depending on the degree of freedom constrained. U(1) will be passed into the routine as the value defined by any magnitude and/or amplitude specification for the boundary condition or connector motion.

KSTEP

Step number.

KINC

Increment number.

TIME(1)

Current value of step time.

TIME(2)

Current value of total time.

NODE

Node number. This variable cannot be used if user subroutine DISP is used to prescribe connector motions.

NOEL

Element number. This variable cannot be used if user subroutine DISP is used to prescribe boundary conditions.

JDOF

Degree of freedom.

COORDS

An array containing the current coordinates of this point. These are the coordinates at the end of the prior increment if geometric nonlinearity is accounted for during the step (see “Defining an analysis,” Section 6.1.2 of the Abaqus Analysis User's Guide); otherwise, the array contains the original coordinates of the node. This array cannot be used if user subroutine DISP is used to prescribe connector motions.
