With the release of Ansys 15.0, you are now able to perform 2D to 3D submodeling in Workbench. This feature will allow the user to compute local detailed results that are not captured using a surface model.
2D to 3D Submodeling: Step by Step
The process of 2D-3D submodeling is very similar to 3D-3D. The user would first create a shell model from his original solid model and then perform his analysis.
After obtaining a solution, the user then creates a detailed cutout submodel from the original solid model.
Once the submodel is defined, the next step is to connect the solution branch from your shell model analysis to the setup branch on your 3D submodel using the Workbench project page. Ansys will automatically interpolate the results from the shell model onto the user specified cut boundaries.
