Hi all,

I want to create a new user field function that calculate the velocity magnitude of only two components which are j and k. The problem is that i don't know how to write the function definition. Specifically, I don't know the funtion names of the two velocity component j and k. If anybody knows the tips, please let me know.

Thank you all.

sqrt($$Position[1]^2+$$Position[2]^2)

I think exponents must be defined like this:

sqrt(pow($$Position[1],2)+pow($$Position[2],2))

The one I was looking for is this:

sqrt(pow($$Velocity[1],2)+pow($$Velocity[2],2))

Thank you all for the tip, really appreaciate it :-)
