Two tutorial examples are provided here to demonstrate how to build CFD meshes using the meshing tools in STAR-CCM+. Both cases represent realistic industrial applications that originate from different CAD data formats and demonstrate the necessary steps to prepare the surfaces ready for volume meshing.
The first tutorial (control valve) illustrates the mesh generation tools in STAR-CCM+ for dealing with a geometry with the following characteristics:
The starting data originated from the STAR-Design software and represents a generic control valve design, commonly used for water management. Two variations of the geometry will be considered, namely the valve in an almost closed position and the valve in an open position. The same polyhedral meshing parameters will be used for both situations. The parameters used to build a trimmed cell mesh are also demonstrated.
The second tutorial (heat exchanger unit) shows how STAR-CCM+ deals with geometries with the following characteristics:
The geometry was again built using the STAR-Design software and represents a generic heat exchanger unit. A polyhedral mesh containing a conformal mesh interface between the fluid and solid regions will be built. Prism layers will only be included in the fluid part.
Additional meshing tutorials will be included with future releases of the software and will cover use of STAR-CCM+ meshing features such as:
