Hello, I'd like someone to help me with the attached file. Because the original file is too larg I cut only the iteration, so there is not actual computing inside, but just the programe code. I created iteration to compute a temperature "T". I use "while" iteration. The iteration has to stop when the difference between the current and the previous value of the "T" is below "1". But I get wrong value with difference above "1"! I check this like doing the computing normally (without iteration). I hope the mistake is mine, and this is not because of the software accuracy. Thank you!
