I have a species which is absorbed in a zero-order manner. I want to model the reaction rate as "UptakeRate*ActiveState". So I can give value of 1 or 0 to ActivateState to control the active state of this process. The species itself is under control multiple processes, so I want to use Event to automatically change the active state of absorption.
However, when I use these two events:
Event 1，trigger: species > 0, Function: ActiveState =1; Event 2, trigger: species <=0, Function: ActiveState=0
The simulation seems to be stuck without stop.
Is there any way to solve this ? Thanks

I don't see any obvious problem with this approach. Can you share the model? Some additional debugging tips would be to set MaximumWallClock and/or MaximumNumberOfLogs to see if you can get the simulation stop. Then, you might be able to inspect the results and see what the problem is.
Update: You can do this in the SimBiology Model App by clicking on Simulation Settings. See the screen shot below.
Hi, Arthur
Thanks for your concern. I am not familiar with coding of SimBiology. Can these two tips be performed in SimBiology APP?
Yes, I've updated my original answer to include information on how to do this in the app.
Hi, Arthur
Thanks for your suggestion. The simulation can stop but the problem still exists. However, I find a way to get round it. I use a Michaelis-Menten equation with a very small km, which does not result in negative species value.
