Hi,

I try to put the hydrologic model I use to UNIX,
There isn't problem when compiling but when I run it, it stops at the
beginning, showing:

CVode-- At t = 0 and h = 0.001, the corrector
convergence failed repeatedly or with |h| = hmin

But I can run it smoothly under windows VC, I changed the maxstep and atol
make them larger, but it seems doesn't work.

Does anyone have some idea what I shall do?

Thanks!

Sheng

Hello Sheng,

Are you saying that exactly the same program runs successfully under
WindowsVC, but not under Unix?  If that is true, then most likely you
have failed to install correctly.  Do not bother changing inputs like
atol.  Try running the examples provided until you find the problem.
