Hi All,

We are looking to suppress any creep from occurring.  Wondered if anyone new this offhand versus me trying tinier and tinier values.

Thanks,

I don't know if I can completely tell what your question is.  But from the subject line, I think you are asking how small TIME can be.  Personally, I have run 0.001.  I don't recall trying to go any smaller.

Hopefully that helps!

BTW I have run like time,1e-8 before.  Just wondering how low I can go.  Time,1e-99  ?  I figure there's some double precision number out there as limit.

Dan,

I've got some old training material which suggests setting time to as small as 1e-8 for establishing initial conditions, and using RATE,OFF to enforce no creep. There are limitations on when RATE,OFF can be applied so check the help for which element types, etc.

Best regards,
