Solved: event time is in past

"createvent: event time is in past: event time changed to present. Object: Source1 advancetime: -11.368785, time: 14109.910037 "

I'm getting an error like this.

There seems to be no way to resolve this error in the "Inter-Arrival time" setting.

How can I set it to avoid this error?

event_time_is_in_past_1.fsm

The same question was confirmed, but I couldn't find a specific solution.

Math.max(0.01, normal(90,36.6,getstream(current))

a normal distribution can return negative values. Then tey are in the past.

You can prevent it with a mathematical function returning a value near zero if the result gets negative.

if you choose deviation parameter value, which is larger than 3 sigma interval in comparison to your mean value, you get negative values.

normal(90,15) chance to get only positive values is ok.

normal(90,60) chance to get some negative values is an reasonable assumption.

＞Math.max(0.01, normal(90,36.6,getstream(current))

My sample model seems to automatically convert negative values to zero without using this code.

However, the error continues to occur.

Math.max(0.01, normal(90,36.6,getstream(current)))

You were missing a close parenthesis character. There are no errors when using this expression.
