Workflow

From flowsheet to engineering insight.

A focused workflow keeps process definition, solving, and result review connected.

  1. 01PFD

    Build

    Create the process flowsheet by connecting feeds, equipment, products, and recycle streams.

  2. 02THERMO

    Configure

    Select components and a thermodynamic package, then define equipment and stream conditions.

  3. 03SOLVER

    Simulate

    Run the connected process and follow equipment calculations and recycle convergence as they solve.

  4. 04RESULTS

    Analyze

    Inspect stream states, equipment performance, diagnostics, convergence, and retained run results.
