I have successfully completed a UEL, 3-D 8-noded linear user-defined element in Abaqus. I still need to verify the results, but it works.
I am trying to visualize the results in Abaqus CAE, and according to chapter 26.15.1 in the documentation:
Plotting of user elements is not supported in Abaqus/CAE. However, if the user elements contain displacement degrees of freedom, they can be [B]overlaid [/B]with standard elements, and model plots of these standard elements can be displayed, allowing you to see the shape of the user elements. If deformed mesh plots of the user elements are required, the material properties of the overlaying standard elements [B]must be chosen so that the solution is not changed by including them[/B]. If this technique is used, nodes of the user element will be tied to nodes of the standard elements. Therefore, degrees of freedom 1, 2, and 3 in the user element must correspond to the displacement degrees of freedom at the nodes of the standard elements.
[B]I am interested in displaying the deformed results in Abaqus CAE. How does one overlay with standard elements? Is it done in the input file somehow, or an the UEL source file?[/B]
