Expression Report
 

Hi, I'm aware there are threads on similar topics but I have not been able to find a solution. What I would like to do is take the velocity data at different positions at different time steps. I'd prefer to make a report to do it instead of having a macro export a table each step, but I don't know how to write the expression. For example I'd like to:
record velocity[x] at given position[,x,y,z]

Thanks for your help.

Expression is the same like a field function.
Before you had this you had to create a field function and then a report for this function.
Now you can create direct a report with a "function" (better expression).
