Hi folks:

Is there any way at all to use NDSolve to solve PDE's with more than 2
independent variables. This is actually very important, because if the
answer is no, then it makes impossible the use of Mathematica in a
huge field: Fluid Dynamics, in which we'd like to numerically model
the evolution in time of the velocity or vorticity field. Depending on
whether there are 2 or 3-D, this could involve 3 or four indep
variables. Is there ANY package or version of Mathematica that allows
this to be done? None of the NDSolve examples in Help have more than 2
variables (x,t). I have version 3.0. When I try to NDSolve with limits
on 3 variables, it complains that it was expecting Options at position
four in NDSolve, not another variable.

maybe from 99 something changed...
