Question: Sounds simple, but I get errors for trying to control DSOLVE,NUMERIC stepsize?!?!?!?!

Hello All,

I am solving a parabolic PDE using the method of lines (not using pdetools) and so I have a procedure that writes out the N ODEs.  The only problem I currently have is trying to monitor the CFL condtion.  In essence I need to know how (if possible) I can control the stepsize explicitly for the dsolve,numeric command.  This sounds simple and I feel I must be overlooking something.  

In the worksheet is more, and better, documentation about what is going on.


Thanks sincerely,
