Efficient simulation of large scale process flowsheets

We have been developing/working with open source process simulators DWSIM and OpenModelica.  These simulators are proposed to be used for (1) steady state simulation (2) dynamic simulation (3) startup shutdown simulations, etc.  Both continuous and batch processes will be studied using these simulators.  We propose these simulators also for collaborative content creation, training a large number of chemical engineering students, and using them in a big way in industry, especially small and medium scale.

The current work involves the following:

• Efficient ways to compute thermodynamic correlations
• Efficient ways to converge large flowsheets to steady state solutions
• Efficient ways to initialise Differential-Algebraic Equations
• Efficient ways to integrate large systems of Differential-Algebraic Equations
