Defining "Time on Streamline" Variable

ashtonJ · March 19, 2015, 23:04

Dear all,
Does any one know how to create "Time on Streamline" variable.

I tried to define an expression "Time on Streamline" and create a variable using this expression. But the following error is given:

ERROR
Variable does not exist.

Could any one help please.

Thanks
AshtonJ

You will have to be a bit more specific than that. Right now your forum post says: "I have a problem, help me".

How did you define the expression? Post the ccl?

Thanks Lance.
First I plotted streamlines (Streamline 1). Then I defined an expression (A = Time on Streamline 1) and finally defined a variable (VA) using that expression. When I use the function calculator to find the value of VA, it gives the error.

Your variable will only exist on the streamline object. So you will have to be careful that you reference it correctly. Also don't forget that you probably have several streamlines in the streamline object so make sure that is correctly handled by your expression and function (obviously it is not correctly handled as you are getting the error).
