- FE Mesh Component 0 is not associated with a CAD Body error
Note: If you are running into the error FE Mesh Component # is not associated with a CAD Body, then you most likely have a CAD Face that isn't associated with a mesh. Continue reading below to solve this issue.
1. Select the CAD Face List overload in the boundary condition block.
2. Use the CAD Face directly as an input or use the CAD Face List block to select multiple CAD faces for scoping your boundary condition.
3. Associate the FE Mesh with the CAD body containing the CAD faces selected in the above step.
- Mesh: The FE Mesh to be associated with the CAD Body.
- Geometry: CAD bodies from which the boundary CAD faces are scoped.
- Tolerance: Tolerance is the Maximum distance between selected mesh elements and the chosen topology.
Associate FE Mesh block also helps you to scope boundary conditions to multiple FE meshes that are generated by duplicating and replacing the Mesh input for the new Mesh. For multi-component analyses, you can use the Associate FE Mesh block to assign different FE Meshes to different CAD Bodies. A Boundary Condition that is scoped to a specific CAD Face will only be applied to the mesh associated with the CAD Face. This is useful to distinguish features that are in close proximity to each other, like neighboring Boundary Conditions or FE Connectors. For example, a Tie Constraint takes Independent and Dependent boundaries which typically overlap in 3D space. Those boundaries can be assigned to two CAD Faces that are in the same location but from different CAD Bodies.
And that’s it! You’ve successfully used CAD face to scope a boundary condition.
