Real-Time Structural FEA Simulation Engine in Web Browsers
Solving large stiffness matrix systems ($K \cdot u = F$) using Rust compiled to WebAssembly combined with WebGPU matrix operations.
Engineering analysis tools are transitioning from desktop software to cloud-native browser environments. Executing structural matrix decomposition directly on client hardware eliminates server compute costs and enables interactive parameter tuning.
1. Sparse Stiffness Matrix Assembly in WASM
Constructing global element stiffness matrices from 3D truss and beam elements inside Rust WebAssembly binaries yields native computation speeds while isolating memory allocation safely.
2. Conjugate Gradient Solvers on WebGPU Compute
Executing iterative matrix solvers (such as Preconditioned Conjugate Gradient) across thousands of WebGPU threads resolves large structural displacement vectors in fractions of a second.
3. Interactive Stress Visualization & Deformed Shapes
Passing calculated nodal displacement buffers directly to vertex shaders enables instant visual rendering of exaggerated structural deflections and von Mises stress contours.
