Hi to everybody.
I've got a problem with an interactive assessment of a parameter.
I'm not able to set in the correct manner a "for Cicle".
The general problem is this one
Procedura.PNG
I need to set an initial lenght L0=6b, than
-if the ratio between y/b<0.1 the cicle end and i obtain the value that i need (y and L);
- if the ratio between y/b>0.1 and <0.6 i need to continue the cicle until convergence
File not found.File not found.File not found.

I'm not able to set the correct fuunction
File not found.File not found.

Someone can help setting for me the formulation?

I attach the file below, need to be open with the related excell

File not found.File not found.

Thancks in advance for any answere!

Hi Ale_Biaso,
Happy New Year to You and to all SMath users and developers!


1. Congratulations for your interesting and useful work.
2. Thanks for the extensive publication of this work.
3. It is not a simple task to check it all. That’s why I kept my first attention to identify the reasons of “red-marked” errors on your sm file.[/list]
4. Here are some identified reasons of such errors.
Simple pragmatic suggestion: when I have such errors, firstly I display the values of each term to see if they are already defined:

d is not an index; L is not defined, etc !
5. I keep ready to look for a further evolution of your work.
Best Regards,
Ioan

PS: If I may adding some suggestions it will be:
* For the working phase, I use "no limits pages" screen
* Separate "the cosmetics aspects" from the basic robust algorithm. Keep this for a distinct operation...

Buona Fortuna,

Ioan

Recast as suggested by Ioan ... attach.

I reply here to your advices.

I tried to semplify the spreadsheet in order to focus aptention on the iteractive process that i'd like to assess.
I explicate even the main process that i tried to set into formulation but that doesn't works because i don't understand the correct syntax of a "for cicle"

All my consideration are into the smath file and summaryzed below.

If someone have time to take a look and fix the mistakes of the cicle only i'll be very gratefull.

I attached the simplify file below (always need to be opend in the same folder of related excel)
Ciclo for semplificato_R1.sm (5 MiB) downloaded 26 time(s).
413-Camino Alabama-Modale_R1.xlsx (300 KiB) downloaded 24 time(s).

Thancks for your time

In fact I see at least two incorrect or suspicious situations:
1) what appears to be an assignment is performed with = instead of :=
2) j of the for loop is a counter but here it is referred to as a series of values ​​with units of measurement. I'll show you a simple working example

Hi Ale,

That's one way to do it (a backbone)

File not found.File not found.


P.S. I'd suggest to use the multiple if/else instead of the nested if/else to improve the readability (just add more argument separators in the standard if/else)
