Steady-State Finite Difference Method (FDM) for Civil & Structural
Apply the steady-state finite difference method (fdm) to real civil & structural problems — in the browser, with AI assistance.
This is the steady-state variant of the Finite Difference Method (FDM). FDM replaces derivatives with difference quotients on a regular grid — simple to implement and ideal for diffusion, wave, and reaction–diffusion PDEs.
In civil & structural, teams face challenges like load and seismic response, material fatigue, wind loading. The steady-state finite difference method (fdm) directly supports use cases such as structural fea, seismic modal analysis, wind-load cfd, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.

- Structural FEA
- Seismic modal analysis
