You are probably allowing the model to set the time stepping "automatically." Don't do that. In the longer time case, the model is probably losing all the physics details by taking steps that are too long. Set the time step manually (and put some thought into choosing it) so it will be appropriate to the physical process you are modeling.

The phenomenon that Robert is referring to is described in some detail inthis blog post, where you will find more information on the solver settings you can use instead.
