In the two attached sheets I add the same problem but in the first the units of measurement are added fictitiously and the solution is correct (verified with other specific software); In the second sheet, the units of measurement are used (including the application of the new functionality of the integrals defined with units of measurement). However, in the application of the second integral I get a double value (I don't know if it is a coincidence) of the expected one.

Ciao Sergio. It seems that you redefine b in the collapsed area, and bb have not the same value in both files.



Best regards.

Thanks Alvaro, a stupid error due to the re-adaptation of the sheet to the new integral functionality with measurement unit. Since I had difficulty solving the nonlinear equation directly with "solve", I used an old manual procedure that inadvertently changed the value of "b" (used as a value to trigger the iterative procedure)
