Simoly: hope some user of your SS version will catch/isolate the bug.

Thank you. But the problem is not because of eval(). She's somewhere deeper. My f3(x) and f4(x) limits are ainterp() of the table data.


Hi avp. Try using eval() for ainterp().

Thanks, this is how the integrals are calculated, but the function containing the integral inside still returns an error. Accordingly, the final result of the calculations still failed to be obtained.

The type errors your version reports is
wrt some limit(s) of the double integration.
Why specific to this version ?

I dont know. I wanted to know here why the calculation of integrals, which used to work well before, broke down after adding the ability to use the dimensions of units in integrals.

You have a good point about units in integral.
Attached is your saved working version.
Open in your latest SS. It may rescue the integrator.
God save the Queen and avp.
Cheers ... Jean.

Hi, Alvaro.
The result is not correct. The result should be Kx = 1.233, Ky = 1.044

Hi avp. I hope the problems with double integrals can be solved, because the calculation of double integrals that SMath had was quite powerful. The only way to calculate Kx, Ky would be to discretize and integrate over the cubic splines curve.

This document is adapted/doctored in native Smath 6179.
It does not scratch Smath a bit.
As you download, after it has finished
it offers to update: click close to be back SS 6179.
Re=download and let it update latest SS.
If you have red as it complained, probably the integrator
is freaked in that version ... hard to explain.
Cheers ... Jean.

... code that test double integration in your latest SS.
Hoping more Collab will code as well to sanity.
