Different outputs with the same inputs #14

I thought that the way GLM-AED works (I am using the newest GLM3-AED2), that you would always get the same answer if you give it the same inputs.... But this does not seem to be the case. I was looking for the effects of changing a P variable (Fsed_frp). When I made the change the first simulation after the change I get one answer (at least one set of plots). Dissolved phosphorus gradually increases until overturn And then when I run it again with no changes, I get different answers. Very different dissolved oxygen and almost no dissolved phosphorus Are there any random number generators in the code that could lead to this?
