Debugging help needed - Getting error message on variable in formula, but when printing separately the value is there - Сообщения
#1 Опубликовано: 16.11.2020 10:19:38
Trying first time with some bigger formula set, but now I have run into a problem with some error propagating into the calculation. Seems more or less lie anything becomes a problem some way down and even if I reformulate the formulas there pops up another problem with a value not being set as shown in the attachment. When I rewrote the formula then another value was marked red.
Feeling like the program is either running out of memory or there is a problem somewhere else causing the problem in the last part.
I saw someone else looking into the text file here on the forum and I see there are some error message there without me understanding how to debug it:

Hope someone have time to tell kick me in the right direction here

Attach the document [no monkey see, no monkey do].
Define the undefined or make the formula dependent of the parameters.

Jean is right.You want something that is very time consuming for other people to recreate the document they see on a screenshot and debug it while the document can be simply posted.

Your numerical engine is scrap from other gyzma(s).
That kind of bug is not possible in native Smath.

Program says μr_O2 - not defined:
Searching for μr_O2:
It is really not defined. This equation is only one place where μr_O2 can be found.
This is an error.

Hello,
As far as I can see I have defined the variable here:
Have I done something wrong in this definition?
When I try to print the variable other places in the document it seems like it is defined since it returns a value of zero (which it should have).
Did a test with different value
and it still is a problem even if the value is defined:
Appreciate all help from you here!

Hi. The error msg is about mr_O2, even red colored another expression. But notice that you define "m.r_O2" not "mr_O2", see the difference in the dot.
Best regards.

Thanks Alvaro and the rest for assisting me here! Finally found the error with your help now. 
I see you use an Unknowns() function, is there some documentation of that one? Did not get same result as you when I tried to enter it.

Hi Terje.
Under Tools / Plugins open the "Interactive Book" named "Interactive SMath Handbook", which it's an extensive and excellent documentation for SMath and almost all it's plugins, by Martin Kraska.
Then look under plugins / Special solvers. There is an entry for Unknows.
Best regards.
