Simulation initialization problem
Thread Content
I once used dynamic simulation software, with initialization settings in the program； Later, with ASPENPLUS, it was also necessary to initialize it each time a calculation was performed ； Many of my colleagues use PROII; they can click to run the calculations indefinitely. I would like to ask experts: is it necessary to initialize ASPENPLUS when performing calculations? If the calculation has converged without initialization, is that considered correct?
1# 92427xl does not need to be initialized; sometimes initializing it each time actually hinders convergence. For example, in the iterative calculations involved in distillation, it is required that there be four nines after the decimal point at the top of the tower; performing direct calculations will result in a non-convergent outcome. You can first set the top of the tower to two nines, and then use the result of the calculation as the initial value for iteration; when you enter four nines again, convergence will be achieved. Personal experiences are for reference only.
It should also be correct. Analyze each situation specifically; as long as it helps bring about convergence, that’s good.
