What is convergence in ASPEN PLUS?
Thread Content
Could you elaborate on the concept and applications of convergence?
Buy some books and read them; asking questions like this doesn’t lead to any progress
Chemical process simulation software like Aspen consists mainly of thermodynamic databases, thermodynamic equations, unit process models, and mathematical solvers. If you have taken courses related to chemical thermodynamics and chemical separation, and if you have tried to solve some simple thermodynamic equations and distillation column models, then you should know that it is not possible to find analytical solutions for these model equations; instead, iterative methods are used to solve them. Convergence means that, within a finite number of iterations, the accuracy of the iteration results reaches the specified error level
