I failed when I used Parameter Identification with the following result ：Simulation did not produce results

I have had similar issues when parameter value range minimums were set to 0 or when there were more than 8 parameters.

@doctorcsu When you go over with the mouse on Faulted or the Message, do you see more info?

The fact that Infinity is shown and number of evaluation is 0 means that the simulation does not even seem to run with the start value provided. Can you actually run your simulation? Is this PK-Sim or MoBi?

@SteTindal This should not be the case. The number of parameters should not play a role unless the PI is setting some parameters to values that make the simulation diverge.

I had a similar error when I tried to input several simulations (n=16) together in PK-Sim.

@msevestre do you have any insights about what could be the problem?

When I did the PI for the drug residuals in tissues (n=8) it worked pretty well, but when I combined tissue and plasma simulations to perform a second PI (n=16 simulations), this error message appeared.

Would you be willing to share the project?
If yes , this would be extremely useful for us to understand. I can also send you a link for private upload if you prefer.

[bruni-cris]

Yes, please send me the private link, so I can share more information

Just sent it. Thank you very much!
