Hi everybody! It's my first time in the forum, even if i read very often your adviceses. I'm trying to do a dual stream heat exchanger simulation with the radiator that we use on our FSAE car. I'm following the star ccm+ tutorial "dual stream heat exchanger" but i have problems meshing my geometry. I modeled with solidworks the radiator, the "coolant top" and the "coolant base" that we can see in the picture and i did an imprint operation to generate the physic contact between radiator top face and coolant top/base base faces, then i assigned parts to region and i set the interfaces. The surface mesh runs, but when i try to generate the volume mesh i have an error saying "edge attached to an odd number of faces" and visualising in "representation" the remeshed surface i have the free edges that are showed in the picture:

How can i fix this error? Thank you in advance

Your picture is not visible. But from what I understand, You have non-manifold edges error. Check in surface repair that where you are getting these edges/faces. You can try to repair it there itself or go back to CAD to get good surface.


Hope this helps.
