Re: Randomized noise seed crashes model

All levels are behaving as expected. As I said, this happens at time 0.000 (which is initial time), and setting noise seed to a constant removes the problem. Wouldn't it be reasonable to suppose that the connection to a function that actually uses noise seed (i.e. random uniform()) is genuine?

Re: Randomized noise seed crashes model

I was probably not correct to say the model "crashes"; it terminates with an error message "ERROR: Floating point error computing - rYear - at time = 0.000000. ", where rYear is integer( RANDOM UNIFORM( 1987, 2009.9, 0)) If I remove the random uniform function in rYear, the next ...

Randomized noise seed crashes model

Hello everyone... I am trying to set the noise seed in my model to randomize off the timer on every model run, using GET TIME VALUE(2,0,10). However, this results in the model terminating with an error at initiation (time 0.0). The error is thrown by any variable that incorporates a RANDOM function ...
