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.
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
Abaqus/CAE Usage Load module: Create Boundary Condition: Step: Initial Using the direct format You can choose to enter the degrees of freedom to be constrained directly. Input File Usage Either a single degree of freedom or the first and last of a range of degrees of freedom can be specified.
So if you define a cylindrical coordinate system, at a particular point U2 = tangential displacement, UR3 = rotation about local "z" axis (axis that runs throught the point of interest and is parallel to the cylindrical coordinate system axis).
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
Abaqus ignores them. If your model is anything similar to figure 3.10 (your attachments), then the boundary conditions at the bottom edge are U1=0, U2=0 and U3=0 ( your Y axis is vertical). All KO70v.
