Please help, I know you can

The first error message is in Function_Prop
It says "must be a real number" ?

It`s file without first error, you can use it.

... does not either SS 6179.
You may replace Function_prop(P,T,M) by the Spline Matrix
Collapsed in red ... try some suite from there.
Watch unit system [not my cup of tea !]

As it looks, you are attempting to integrate kg/m³ over 'p'
for the given 293 °K ... done otherwise finite differences.
In your solve block, vary many things are constants that could
be simplified but so many are undefined.
What should this solve bloc should do wrt the integration ?
find an intersection wrt some 'P' or else ?
The meaning of the cumulative integration reads like this:
"for °K 293, accumulate the kg/m³ over the 'p' range'
In other words: the cumulative mass-flow kg/m³over 'p' range

I don't understand you. What should I do? Or, if You can, please correct it

This is the correct response to the variable that should be obtained in the Solve function

Function_prop(P,T,M) does not work.
Use the Spline Matrix in lieu
I understand nothing in there.
Hope Collabs read and have some ideas !

I don`t understand too. May be anyone have any idea?

I fixed Function_Prop using InterpBilinear() from the Statistical Tools plugin. Note that the definition without line operator behaves buggy, because you even won't get the usual storage preview when hovering over the definition. This is strange and indicates something really bad under the hood.

Yet fixing the function doesn't solve any of the problems downstream. But given the strange error messages and bugs I'd say build 7251 can't be used safely anyways.

BTW, instead the if-else cascades I'd recommend using the selection index as index of a vector of options.

Perfect, may be you can solve "SOLVE" function in this program???

1. Up to this point: NO ... μ.др is undefined
2. If μ.др has a value: plug it in this document.
3. Please, don't re-post your original, so I can do more
from this document.
4. Units don't match in this project.

... look closely at the point we are.
Define the base viscosity μ.др
The complex term is most puzzling ?

Sorry. I understand you, I didn’t write it down. instead of μ.др . -> μ.тр

Sorry. I understand you, I didn’t write it down. instead of μ.др . -

... now that we have the base viscosity, we can plot/tabulate "Bloc".
From there, given some value in "Bloc" we can solve for the pressure
that creates this value .
Cheers ... jean
Does it make you progress in your project ?

The answer does not match, it might be better if I attach a file from MathCad. I have to translate the program from MathCad to SmathStudio, but sometimes I get errors like this.

Here is the answer, sorry, that in Russian

... then check if the "Bloc" you have constructed is OK.
Tabulate the Mathcad "Bloc" that you have translated Smath.
My working Mathcad is 11 not connected to Internet,
My XP Pro. has no AV . If the two MCD/Smath blocs don't
agree/tabulate same: then your translation is in doubt.
Cheers ... Jean

Your Smath ρ vs pressure [p] does not correspond to MCD.
I can't help more from so much not clear.
Check with Viacheslav, he is with MCD ... Maybe Radovan too.
Cheers, best ... Jean
