# Design with Finite Elements. Lecture 2: How to model with FEM

- SDC Verifier is different in the lecture slides than then current SDC verifier
- Element stress vs Nodal stress
- Mesh Size and type
- Warping and torsion
- How detailed should the crane be modelled?
- Modeling details: Stiffeners, Mass distribution, Hinge points and plate hinges, Stiff connections and constraints
- Modeling: Beam simplification: No stiffeners included
- Mass distribution How to add the engine room
- Can we model this in another way, just show the shape
- How can you make sure that the engine room does not influence the stiffness of the structure?
- Beam release
- Joints and hinge points
- Connecting boom to forestay (Skip for assignment)
- Real hinge points
- Trolley passing construction
- Connection of beams with Offsets
- Constraints Bogie sets
- If the download wb3416_parametric_model.exe does not open use the already installed one
- Difference crane width and support width + bay explanation
- HELP! My model is gone / Active group
- Building curves
- Removing the mesh + meshing
- Apply loads to the crane (gravity, tip load, back load) + how to highlight node where force is applied
- HELP! My forces don’t show
- Constraints bogies to the ground
- Make a job + individual loads
- Load sets
- Load group
- HELP! Error nodes on same spot
- HELP! Error SINGULARITIES (coincident nodes and coincident elements)
- Calculation
- Matrix introduction
- Make a plot
- HELP! Where do I click on SDC – not responding
- Store / manage views + deformation
- Linear Calculation core: Load combinations quick calculation method
- See maximum result: load group
- HELP! Strange displacement in my plot
- What use SDC Verifier for
- I want to build a latice structure in my model
