I am attempting to model the conjugate heat transfer of water flowing through a steel pipe using the chtMultiRegionFoam solver. I successfully ran the chtMultiRegionFoam tutorial, so I have a relatively good grasp on the solver; however, I am having issues with the makeCellSets.setSet file that accompanies the solver.

From what I understand, makeCellSets creates rectangular-prism regions in the mesh using the boxToCell command. For my problem, I need a cylindrical region through the center of the mesh for the water to flow through.

Is there a command other than boxToCell that will allow me to create this cylindrical region in makeCellSets? If not, is there a way other than makeCellSets to create regions in a mesh that will work with the chtMultiRegionFoam solver?

Here is my simple code for the makeCellSets.setSet file:

Code:
cellSet water new boxToCell (80 80 0)(-80 -80 10)
cellSet tube clear
cellSet tube add cellToCell water
cellSet tube invert
Thanks in advance!

Hi Matt,

Try using the surfaceToCell. Further instructions can be found in the cellSetDict file under applications/utilities/mesh/manipulations/

Thank you for your reply.

I used the cylinderToCell command in cellSetDict and it solved my problem!

best regards,
Matt
