Hi

it's that you have reach some kind of singularity, but there are many possibilities,
insufficient BC,
or BC that change and go through critical valus,
cases when the results say 0=0 (not easy to decide where to go from there) ....

Good luck

Hi,
Thanks Ivar. I missed out one boundary condition while solving that happened to trigger this error.
