Implicit Finite Difference Method (FDM) for Chemical & Process

This is the implicit 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 chemical & process, teams face challenges like reaction control, mixing efficiency, safety margins. The implicit finite difference method (fdm) directly supports use cases such as reactor modeling, distillation transport, combustion analysis, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
