To edit an existing base motion boundary condition using menus or managers, see Editing step-dependent objects. In the Basic tab, select the Degree-of-freedom to specify the direction for which the base motion is being defined. This direction is always a global direction: U1, U2, U3, UR1, UR2, or UR3.
Antisymmetry about a plane with X = constant (U 2 = U 3 = UR 1 = 0; Abaqus/Standard only). YASYMM. Antisymmetry about a plane with Y = constant (U 1 = U 3 = UR 2 = 0; Abaqus/Standard only). ZASYMM. Antisymmetry about a plane with Z = constant (U 1 = U 2 = UR 3 = 0; Abaqus/Standard only). PINNED. Pinned (U 1 = U 2 = U 3 = 0). ENCASTRE
You must assign an element type key to a user-defined element. The element type key must be of the form Un in Abaqus/Standard and VUn in Abaqus/Explicit , where n is a positive integer that identifies the element type uniquely. For example, you can define element types U1, U2, U3, VU1, VU7, etc.
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.
course, and in principle ABAQUS should be able to find them, but it is not coded to do so. To demonstrate that this is the cause of the problem, in the Load module create a new BC that will constrain the displacements on the inner surface of the lowest hole in the wheel (see the figure). Prescribe a displacement U1=U3=0, U2= - 0.005. Then return to
