Process Simulation Software

Digital twins of chemical plants. The software chemical engineers use every day: Aspen Plus for steady-state flowsheets and thermodynamics, MATLAB for modelling reactors and control with ODEs, and COMSOL for multiphysics (flow, heat, mass transfer and reaction in real geometry) — with working scripts and workflows.

• Aspen Plus — Aspen Plus is the industry-standard steady-state process simulator. Learn the workflow (components, property method, flowsheet, specifications, run), choosing a thermodynamic model, the Rachford–Rice flash every simulator solves, unit-operation blocks, design specs and sensitivity analysis, convergence of recycles, and Aspen HYSYS/Dynamics.
• MATLAB — MATLAB is the chemical engineer's numerical workbench. Learn to write mole and energy balances as ODEs, solve them with ode45/ode15s (stiff systems), fit kinetic parameters to data, solve nonlinear equations with fzero/fsolve, and simulate control loops with Simulink — with complete scripts.
• COMSOL — COMSOL Multiphysics solves coupled PDEs with the finite element method in real geometry. Learn the modelling workflow (geometry, materials, physics, mesh, study, results), coupling flow + heat + species + reaction, boundary conditions, mesh convergence, and verifying against analytical solutions — with a scripted example.
