Meshing: Multi-Part Heat Exchanger
This tutorial demonstrates how to use the surface and volume meshing tools while working with multiple parts within Simcenter STAR-CCM+.
Starting from a Parasolid Transmit geometry file, build a multi-part polyhedral volume mesh with prism layers. Define the appropriate surfaces, create a mesh for each part, and a conformal mesh at interfaces between parts.
The heat exchanger unit to be meshed contains multiple fluid flow passages connected by two end chambers, one of which is split to force the flow around the system. The flow domain is contained inside a solid cylinder, which is hollow on the inside. Two separate bodies are contained in the single Parasolid Transmit file. These are the fluid and solid parts of the geometry.
The heat exchanger geometry is shown below. The case is symmetrical so import and mesh half the geometry, only.
