Add iterator to brute force initial conditions

[quantifish]

Rather than user specifying the number of iterations could just iterate until the init nums stabilize within some tolerance (using a do/while loop or whatever)

[smartell]

You don't want to do this if it involves dvariables. Reason is that the derivative information will be corrupt if you have a variable number of iterations. Unless you write the associated adjoint code, you'll have to use a fixed number of iterations to preserved the correct derivative information.

Ah huh makes sense, thanks Steve. Perhaps I could add a little snippet of code at the end that ensures that the number of iterations used has resulted in equilibrium numbers at length and throws an error code if not.

Or solve the system of linear equations.

Or that. Could be tricky with different things happening in different
seasons etc.

I see your point now. I guess if you want to avoid writing a bunch of basis functions, then a numerical solution is the only alternative. Hmm, you could throw an error code I suppose, but you don’t want it to crash per say. I’d just keep track of the delta’s in each iteration, then print out the value of the delta to the report file, or the screen if it is !=0.

Yah good call, I'll go with that. Cheers mate
