the .org version is very usefull for cht because of it's structure

Hi everyone, is there some magic trick to stopping and restarting a pimple time run in an outer while loop? I'm trying to program a selective frequency damping code that iteratively determines the correct control coefficients (by rerunning a transient simulation for a couple of times) and applying them, but when I set the endTime to the current time (with runTime.setEndTime()), I get errors in MPI. Alternatively, if I add function objects, it keeps on running without printing or exporting anything. I had expected and hoped using this endTime function would be similar to just modifying endTime in the controlDict during a transient run.

use

GOTO

or

BREAK

statements

not sure if you're serious

I am serious. He's trying to stop the outerIteration cycle by forcing a Time (=endTime) that's already running (so you are already at endTime + deltaTime). It is simpler to just use an if ... break or GOTO statement to get out of the inner cycle (outerIteration). Once things work, you can always create a new Time class with the desired effects. Boomer programming is not necessarily bad programming

it usually is if you use

goto

break

is fine though

Why?

I mean,

goto

can be fine, but the big problem is that it's very easy to use it in a very not fine way and modern programmers don't like that

So dont use it in a "very non fine way"

the attitude has changed from "just don't mess up" to "you will mess up, so just use a system where that's harder to do and the problems are easier to spot"

goto

spaghetti code is a debugging nightmare

break

is predictable

So don't write spagghetti code. GOTO doesn't produce spagghetti, bad programmers do. Besides, from what I understand from the original question, the guy wants to jump from inner to outer to again inner iterations according to some parameters he/she monitors: break helps you out, but doesn't bring you back in....

and subverting existing flow control solutions with

goto

is exactly how spaghetti code begins

the only reasonable use for

goto

is if your language of choice doesn't provide

break

, or else if you need to break out of multiple nested blocks

There's also a

comefrom

statement https://entrian.com/goto/

Thank you all for the quick replies! It seems I solved the problem... Last night I was sure this was the problem, but this morning I figured out it was how I reset my velocity field 🙃 For now it seems to work by just using the last results

Just for the sake of completeness, can you exactly describe the working solution?

Of course; Within the time loop I still set the end time using runTime.setEndTime() and it properly stops at the specified time. After the time loop, in the outer loop, I initially reset the velocity field using the field stored before the run. I commented that out and now the run does not stagnate or crash. Hope it helps 😄

But your velocity does not reset, where you wanted it to reset in the original version? How do you achieve that bit now?

Sadly I'm not able to reset the field at this point, but it was not a necessity. For now my paper deadline is more important that figuring that out.

Pro tip: If you don't code for a while, be prepared to burn some extra calories to get the stone rolling again.

Let me know if there is a better data structure for this https://cdn.discordapp.com/attachments/814043123810304041/1367758836064194622/image.png?ex=6815c02e&is=68146eae&hm=395f3a25a85f1531895231f501f538709b25c9f1b2b001f645d3622d148f30e4&

LabelLabelList

Isn't going through a list gonna be slower? 🤔 Although, list is not too large, so maybe does not matter..

Today I learned that

sortedOrder()

can't sort a

List<double>

. Use

SortList.indices()

to get the indices of sorted list items.
