The program uses state-of-the-art zig-zag formulation to predict the stresses in the adherends and the adhesive interphase. Unlike the conventional finite elements, the entire scarf/joint repair is modeled by a "super element" technology that combines the adherends with the adhesive interphase. In another words the entire scarf/joint is represented by these super elements. Since the super elements are internally generated, the user only needs to provide geometric information and material properties. The program is computationally highly efficient. This program assists users in creating input files for CSR, running the simulation and analysis, and viewing the resulting data in interactive two-dimensional and three-dimensional plots.

Users can interactively view the simulation as the input file is written, viewing a 2D representation of the geometry along with 2D/3D view of the generated mesh. After running the simulation, deformed results can be viewed in a 3D plot. Additionally, a postprocessor can be run to allow for 2D results (stress, strain, curvature, etc.) to be plotted. Currently, the higher order zig-zag formulation used in the scarf joint/repair analyses is incorporated into Abaqus as a user element.
