We will also be covering the importance of checking for convergence and making sure that the solutions determined by Aspen are reasonable. We will be using our simulations from the previous tutorial to cover these topics. Checking Simulation Results: One of the most important things to remember when using a computer simulation program, in any application, is that incorrect input data or programming can lead to solutions that are "correct" based on the program's specifications, but unrealistic with regards to real life applications. For this reason it is very important that the user complete at least some very basic checks and balances to make sure the simulation results are reasonable. At the end of Tutorial #1 we had completed a simulation of the first mixer in our acetone separation process. Reopen your simulation because we did not discuss checking your results. For this reason we will rerun our existing simulation. To do this we must first reinitialize our simulation in order to delete the existing results. This can be done by going to Reinitialize. After selecting OK for both of the windows that pop up when you select the reinitialize option, your simulation will be reset. Now that the simulation has been reset, run it again. By using the next button to run the simulation, the program will show you information about its convergence in a status window that otherwise does not normally appear.
