Conveyor Tutorial Flow Rate

Damon in STL · September 19, 2014, 10:43

Just starting to work with CCM+ and working with the conveyor tutorial.

For the Particle Flow Rate Constant.....what do each of the variables "$Time < 0.5 ? 100 : 0" mean?

So, no one knows what the base user functions mean....or where to find their meaning? Can someone point me in the right direction to find this info?

There is only one variable that is $Time which is a scalar in Star-CCM+.

The other tidbits are Java formats. Basically it is an if-then-else statement.

If $Time<0.5
then result is 100
else result is 0

So is that line of code supposed to work as is when typed in as a value?

I am using STAR CCM+ V10.02 and it doesn't seem to accept it.

Thanks,

It worked with a version of 9.06.009.

When you say Star-CCM+ is not accepting it, do you mean it gives an error message? Or does it default back to some constant?

It would give me an error message and say something about trying to put in an invalid field function.

I messed with it for awhile and got it to work, I think taking the spaces out of the code fixed it. I had spaces in it as it appears in the tutorial and that seemed to be causing errors.

"$Time < 0.5 ? 100 : 0"

Thank you for your reponse.
