hi,
I'm a beginner
I get an error in the calculation

error :
result is above max. Allowed positive number

How can I solve it?

Change your calculation result from symbolic to numeric.
You can do it with eval() since they are all numbers.

Thank you
I understand the cause of the error

eval() is a general rule but an absolute rule.
Many projects fail from eval(,).
SS 6179 does not complain as you constructed.
eval(,) is applied afterwards to isolate/accelerate.

Good application case to globalize within the program.
... in my SS 6179 timing drops from 2.6 s down to 1.6 s

Thank you.
I was able to calculate the frequency characteristics
(PP2.sm)

But when I modify a circuit, I get an error even with eval.
(PPS.sm)
it's very difficult.

... sorry, can't help: this document opens freak SS 6179.
You seem to put too much that can't be debugged piece wise.

Hi Takez. Yes, it's very difficult recognize or even guess where the program needs some evals. Also, putting them everywhere make unreadable the procedures. In the case of your PPS.sm that's SMath stores into Z without eval



and this with it



So, for PPS.sm there is where you need to use eval, and seems that then all other calculations works.

Best regards
Alvaro.

Razonar's is the correct solution.
