Simcenter Reports: Per Region

Hello, I want to create a report that displays the volume flow rate through each of the four arms of this manifold Smiley Happy


Thus far my attempt was to create an idealized body. Split body across four arms. Create new surfaces offset at 0 mm from cut plane surfaces. Lastly, unite solid bodies back together. In Simcenter Coupld Flow-Thermal .sim file, I specify Inlet, Opening, Fliud Domain (on the single solid body), and a Report with the four new surfaces selected and "Mass and Volume Flow" in 3D Flow options.


This approach gives me errors. So, is there a step I am missing, or is there a better approach altogether?


Thank you in advance for the help,
