Hi,

I would like to calculate the difference of an output between each consecutive time steps. Do you know how to do it with fudaa ?
I try to create an additional variable but I dont know what expression to use for the time steps and if it is possible.
I would like to find a better solution than to extract the output for every time step and calculate each difference one by one...

Thank you for your help

Hi Elsa,

This is trivial in BlueKenue.

Select your variable in the WorkSpace,
Launch the Calculator, "Tools->Calculator"

Assuming you have 100 time steps,
Assuming your variable is TRACER,
Select TRACER as variable A and set Start to 1 and End to 99
Select TRACER as variable B and set Start to 2 and End to 100
Set the expression to B-A
Provide a Result Name
Hit the Evaluate button.

Hope this helps... Martin
