How to fill out finite element stiffness matrices

How to fill out finite element stiffness matrices

1. Begin by defining the geometry of the finite element model.
2. Determine the type of element (e.g., 1D, 2D, 3D) and material properties.
3. Establish the nodal connectivity (which nodes define each element).
4. Calculate the element stiffness matrix using the appropriate formulation (e.g., based on the material's elasticity).
5. Integrate over the element volume or area to assemble the stiffness matrix entries.
6. Apply boundary conditions and loads to the global stiffness matrix as necessary.
7. Assemble the global stiffness matrix from individual element matrices.
8. Verify the stiffness matrix dimensions and properties (e.g., symmetry) before proceeding with analysis.

Who needs finite element stiffness matrices?
