Hello ! I'm not familiar with mathemaica 2.2, but I have to solve some problems concerning Liquid Crystal Phases ... How is it possible to get the value of t in this Error message into a variable ? NDSolve::ndnum: Differential equation does not evaluate to a number at t = 1.61292. => After this Step I want to have the value of 1.61292 in an other variable like, e.g. upperlimit. This is nessesary for my further Calculations. If *ANYBODY* knows how to solve this problem, please answer :-) Many thanks in forward ...
