Element Stiffness Matrix Simulator — 1D Bar Element
FEM & Optimization
Get a feel for the most fundamental building block of the finite element method (FEM): the stiffness matrix of a 1D bar (truss) element, [k]=(EA/L)[[1,-1],[-1,1]].
Isoparametric Mapping Simulator — 4-Node Quadrilateral Element
FEM & Optimization
Visualize the isoparametric map from the reference square (xi, eta) in [-1,1]^2 to physical coordinates (x,y) and the Jacobian determinant. Move a corner to see element …
1D FEM Shape Functions Simulator
FEM & Optimization
Build an intuition for shape functions, the heart of the finite element method.
SIMP Topology Optimization Simulator (2D Finite Element)
FEM & Optimization
Real-time 2D topology optimization in your browser. Adjust loads, supports, and constraints to explore SIMP method designs instantly.
SIMP Topology Optimization Simulator
FEM & Optimization
Optimize material density in real-time with the SIMP Topology Simulator. Adjust parameters to evolve the stiffest structure using the penalty law and compliance gradient.
Topology Optimization (SIMP Method) Simulator
FEM & Optimization
Optimize material layout with the SIMP method. Set parameters, apply loads, and simulate to find the stiffest structure by minimizing compliance.
