Export of relative velocity magnitude

Hi everyone,


I woud like to export the relative velocity URel magnitude, instead of the absolute velocity U magnitude, in the interfaces files created by TCAE in ../stationnary/postProcessing/interfaceName/0/interfaces.csv. I tried to change the file ./stationnary/system/interfaces. fun by replacing magU by magURel in the list of fields per interface but it did'nt...

Unable to recreate pipe example

I am looking to simulate the power output of an in pipe axial turbine, I don't have any experience in CFD simulations and I've decided to brake down the project into 3 parts, first I am going to simulate just the pipe in which the turbine is going to be housed, then a static state with the turbine in the pipe, and finally setup the rotation of the turbine.


I've made a q...

Also I know that my outlet takes twice the flow that goes in from the inlet, and in t...
