IF programming question

Hi all,

 

For the attached sheet, I am trying to calculate the mid-point of each layer using an if statement. The values are entered using an Excel table. For the first layer, the mid-point is simply H0/2 (so 0.9 m). For the second layer, the mid-point is the previous mid-point, plus the average of the previous and current points (so, 0.9 m + (1.8+1.6)/2 =  2.6 m). For some reason however, the simple IF code I am trying to use doesn't seem to work. I am not very familiar with programming in Mathcad, so any help would be appreciated.

Thanks!

I guess this is what you're after.

Recreate the little program in your Prime, and it should work.

 

Success!

Why isn't the midpoint of the second layer half the thickness of the second layer plus the whole first layer?

(1.8 + 1.6/2)

Both would return the same result, but the if statement still doesn't work because it appears the statement does not store the value for z0. Thanks.

I can't see Prime 5 files.  Can you attach a pdf file?

    After I posted, I realized I am missing a for loop to step through the iterations 🙂 What you posted should work; thank you very much!

    A range variable works like a for loop
