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. Proizvol'noe sechenie_no XLSX.sm (74kb) downloaded 11 time(s).

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.

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. Proizvol'noe sechenie_no XLSX.sm (78kb) downloaded 13 time(s).

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. Integrate Double Didactic Russia (3).sm (75kb) downloaded 10 time(s).
