Lab #7 Boundary Condition (BC) Task 1. Steps Specify type of analysis (linear, statics, nonlinear statics, normal mode dynamics) icon: Left column, Row 1 (L,1) Apply BC's and loads Create BC set (L, 6) 2. Geometry vs. FE based Option when first creating a FEM Can change by: Turning menus on > manage > geometry only off/on > menu off Geometry based : Assigned directly to geometry. It is independent of mesh (if you make modifications to the design, the mesh and BC's will update). Example: surface, edge, vertex, location on edge, location on surface FE based : directly applied to mesh. Locks the mesh. If you change the design, the FEM will NOT update. Example: element face, element edge, node, beam element 3. Restraints. a. If you restrain a node or a vertex the following window will pop up. This window will allow you to restrain all degrees of freedom (clamped), or selected DOF's (ball joint, pin, …) . If you want to restrain the node/vertex in DOF not listed, select the "specified" option and then go to specify restraint.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
