Complete workflow demonstration:
- Step 1: Mesh generation (10×10 structured grid, 200 Tri3 elements)
- Step 2: Element creation with thermal conductivity property
- Step 3: FEM assembly (stiffness matrix K)
- Step 4: Matrix extraction for external solvers (DifferentialEquations.jl)
- Step 5: Solver configuration
Problem: ∂u/∂t = α∇²u on unit square
BC: u=0 on left edge, natural BC elsewhere
Shows exactly what Chris Rackauckas requested in Issue #183:
a) Spatial discretization
b) Stiffness matrix assembly
c) Extracting K, M, f for external ODE solvers
Academic usage: demonstrates JuliaFEM as discretization engine
* Simple linear static example to be shown in SMP18
* Improvements based on Jukka's review
* Fixing spacing after Literature.notebook run
* Adding ## Testing at the end of the example to make sure that something breaks, if the results will change
* Update linear_static.jl
Some little tweaks, mainly making that filter function more understandable.
Use FEMBeam.jl to solve beam problems. Added an example, where
natural frequencies of frequencies of 3d frame structure are
calculated. Some minor modifications to Modal analysis is done to make
Xdmf writing of 6 dof nodes work.
Let's use Literate.jl to automatically generate usage examples.
* Automatically generate documentation from other packages (first try to include each package's docs/src/index.md, but if that fails, then use README.md to introduce the package).
* Add example how to calculate local element matrices.
* Add example how to perform 2d contact analysis.
