Hi everybody,

I read tons of threads regarding integration in CFD-Post but I haven't found a straightforward answer for the question: "How can I change the integration variables in CFD-Post?". Is there a CEL construction which I can apply, or should I do the variable change manually?

Problem definition: 2.5D natural convection annulus flow, with lower part of the annulus being the heater with prescribed wall heat flux and upper walls being the cooler with prescribed temperature.

Further information: in my problem, I need to integrate dimensionless radial velocity through a dimensionless radial variable, since I have non dimensionalized the system. I already know I will use the lengthInt(variable)@ 1D location function. I have initialized the turbo mode in order to use polar/cylindrical velocities. Afterwards I will use this calculation result to assess the local nusselt number, and again I will need to integrate over a different parameter, in this case, the angle.

Any short/long answers?

Thanks in advance, any help or thread references would be really appreciated!
