Of course, but when talking mathematics, the point is not to find the guilty person, but to figure out what the problem really is and how to solve it best, so "answering the question that should been asked" is sort of an industry standard in such cases. I do not see why scicomp should be any different. You shouldn't turn your brain off when following an advice, no doubt, but you should also try to turn it on as much as you can, when giving it :) | |

And if your main concern is well-posedness then scicomp is probably not the best place. For computing solutions, existing software is often a good place to start; that doesn’t mean you should turn off your brain when you use it. | |
| May 15, 2019 at 23:40 | comment | added | fedja | "I recommend posting questions like this on scicomp.SE" I would agree if not for the answers Matt got there now. Nobody there even bothered to ask him for the specifics of the problem or give a momentary thought to the existence and uniqueness issues yet, while it is rather clear that the problem is ill-posed at least in some cases. The advice he's getting there so far is the worst possible one: "just type the problem into some existing software or apply some generic scheme and hope for the best". I hope that will change, but right now I feel that even my stupid questions make more sense :( | |
