RE: 25-MAR-2017 SolveSys - Equation Library and Nonlinear Systems Solver
Thank you for sharing your great app with us, Han!
I've used it successfully for some stiff systems. In such a system, it sometimes gets lost and returns complex values for a system that has real solutions. Changing guess values eventually gets it to converge to the correct solution. In a future version might you be able to add a way to limit the value of each variable...such as "real", and a range? Another non-linear system solver I use regularly implements these restrictions, and it is often helpful. The default of +/- infinity usually works, but imposing a realistic range really helps with some systems. Again, thank you for sharing your app - without your app and its capability, the Prime is very limited for an engineer. |
