Since the surface remesher and volume mesher models have been selected in tandem then we could proceed and generate both meshes in one go. However, for training purposes, we will first generate the surface remesher mesh and view it before proceeding with the volume meshing. To do this, either:
The output of the surface remesher will be shown in the Output window and status shown in the status bar. When the process is complete, the message Surface Remesher Completed will be shown in the Output window.
To view the remeshed surface representation, do the following:
The scene will be updated to display the triangulated surface for the heat exchanger unit geometry.

Surface curvature and proximity based refinement is visible on the curved parts (ie the pipes) of the geometry. The properties of the remeshed surface can be seen by clicking on the appropriate node in the Representations node.
