Hello,

I have a rectangular geometry with several channels, which water is supposed to flow through. Other than the channels, the rest of the geometry should be Aluminium. The geometry is imported from SolidWorks as a STEP file.

I am trying to investigate the heat transferred and the flow of the water but I encounter the problem when the geometry is imported, it becomes one whole domain, thus creating problem when I'm trying to assign water as material inside the channels.

My question is, how can I separate the channels into a different domain? I tried 'split' operation but did not seem to work.

Turn out I just did not cap the faces of the channels.
