Abstract
A method of chemical process simulation includes providing a Sequential-Modular process simulator having a simulation algorithm. Responsive to receiving a process flowsheet creating a directed graph (DG) which represents a topology of the process flowsheet with components interconnected as nodes and process streams including recycle streams represented as cycles, with dependencies between process streams adding cycles. Partitioning the components into a first portion including strongly-connected component groups (SCCGs) along with individual components. An initial location is provided for each cycles for the SCCGs to generate a directed acyclic graph (DAG). An initial calculation order is determined for the flowsheet from the DAG, including an order for calculation within the SCCGs themselves. The SCCGs and components as nodes and process streams as edges with a graphical indication representing each cycle for the SCCGs along with the initial calculation order are graphically displayed, wherein the initial calculation order is user modifiable.
