Aspen initialization issues and convergence problems
Thread Content
When should initialization be used? Does continuous operation convergence use the results from the previous calculation? During the simulation process, I first perform calculations, then modify the algorithm and parameters, and perform calculations again – does this have an impact on the results? I encountered convergence failure during simulation; I changed the parameters and the number of iterations. Should I proceed with further calculations, or should I initialize everything again? I’m a beginner in Aspen; I hope the experts here can help me.
I’m here to help you improve; I hope the Haichuan community can assist you and many others!

As the name implies, the calculation starts from an initial set value； If it is not initialized before running, the calculations start using the results from the last calculation and the newly modified settings as initial values. In my view, initialization is mainly aimed at making the results converge more easily. Whether initialized or not, as long as it shows \"results available\", the results are generally consistent. Unless there is multiple steady-state behavior in the system.
