We have a complex system of equations were only variables >=0 make physically sense. ( seven variables six equations ) We get solutions, but for a certain range of the leed variable one or more variable is negative for all of the solutions . We find no way to force all variables to be >=0. The system has a solution with all variables >=0 because we have a experimental result. The Mathematica solution does not simulate the experiment. I would appreciate help. E. Frauendorfer Fachhochschule Ostfriesland
