Now I want to systematically vary some of these parameters using a Monte Carlo approach. The easiest way to do this would be to just create a small addendum to the dat file that redefines / overrides the parameter values that were previously defined in the dat file, and to paste these two together. Unfortunately, that doesn't work, the solver just complains that a parameter was already defined. Include parameters Xnormal and Xadjust along with parameter X. Read in Xnormal and Xadjust instead of X. Have X computed from Xnormal and Xadjust. -- Michael [email protected] "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards
