For Loop Inside A For Loop

[dimos94]

Is it possible to execute all the iterations of the inside for loop for each iteration of the outside for loop? I have attached a screenshot of my program if it helps. If it is possible could you tell me how to do it plz?

What do you mean by "all the iterations"?  The way you wrote it, it'll execute the inner For loop "Section Number" times for each zero to "MAX L".

I have 30 sections and the max L is 40. I want to get sum of the 30 sections for each 0-40 L and then to plot all the sums. The program doesnt work. It gives me nothing.

What do you mean by "nothing"?  The values are 0?  The outputs do not show anything?

[dimos94]

Yes the outputs do not show anything.  There is something wrong with it but i cant find the problem. Could you help?

Activate highlight execution and retain values and you might be able to spot what goes wrong. E.g. if the array is empty it will calculate 0 times.

Else it'll be alot easier to help you if you post the VI with some typical values set as Default values.

One thought I have is that I think you want those feedback nodes reinitializing for each iteration of the outter loop.  Personally, I would change them to be shift registers (it would clean up your diagram a little bit).

Ok. I attcached the VI. My system has 300 sections. The formula node provides me the power of each section. With the inner loop I get the power for all the sections. The sum is the power of all the sections together. One of the input values in the formula node is the "L". I want the program to calculate all the power sums for all the "L" different values.

crossrulz your suggestion worked. Thx a lot.
