A list of the boundary conditions used in ABAQUS. U1, U2 and U3 specify movements along Table 1. UR2 and UR3 specify rotation about the x, y and z axes, respectively.
How do i use spatial displacement of nodes as displacement values in Abaqus? I obtained the nodal displacement values of (u1,u2,u3) from a bar in an analysis. I want to use these spatial

If you model the part with generalized plane strain elements, you must use the Keywords Editor to apply boundary conditions on the active degrees of freedom (U3, UR1, and UR2) at the reference node of these elements (see Adding unsupported keywords to your Abaqus/CAE model).

XASYMM Antisymmetry about a plane with X = constant (U2 = U3 = UR1 = 0;ABAQUS/Standard only). YASYMM Antisymmetry about a plane with Y = constant (U1 = U3 = UR2 = 0;ABAQUS/Standard only). ZASYMM Antisymmetry about a plane with Z = constant (U1 = U2 = UR3 = 0;ABAQUS/Standard only). PINNED Pinned (U1 = U2 = U3 = 0).
The fundamental units in the SI system are length in meters (m), mass in kilograms (kg), time in seconds (s), temperature in degrees kelvin (K), and electric current in amperes (A). The units of secondary or derived quantities are based on these fundamental units. An example of a derived unit is the unit of force.
Assign restraints (U1, U2, U3, R1, R2, and R3) to joint G, then assign displacements obtained from the global model to joint G through Assign > Joint Loads > Displacements. Analyze the local model for the applied displacement loads.

YASYMM: Antisymmetry about a plane with Y = constant (U1 = U3 = UR2 = 0;ABAQUS/Standard only). ZASYMM: Antisymmetry about a plane with Z = constant (U1 = U2 = UR3 = 0;ABAQUS/Standard only). PINNED: Pinned (U1 = U2 = U3 = 0). ENCASTRE: Fully built-in (U1 = U2 = U3 = UR1 = UR2 = UR3 = 0).

Hi Sadeq, In the boundary conditions dialog box, there is an option of choosing coordinate system. If you have chosen (the default) global coordinate system, then U1=Global X, U2=Global Y and U3=Gloabl Z. But you have the choice of selecting any of your own coordinate system, in which case U1,U2,U3 will take on those directions. Regards, NSK
