Trying to solve a systems of 3 equations with 3 unknowns by means of SOLVE BLOCK and MINERR function. (or find). It doesn't provide any error message but it seems not to calculate any root; it simply provides the three guessed values as the results without running any iteration.

Thanks a lot for you great help!

Despite the example has taken from a technical manual, you're right that equations have been manually modified...

Unfortunately I've already tried  with these new set of equations (i.e. for stiffened liners) but I get almost the same results; not convengerce or imaginary solutions.
