convergence failed when put the model under UNIX

[Sheng_hz]

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!
