Overset Meshes
• Allows for the study of
– Bodies with extreme ranges of
movements
– Configuration changes
– Part replacement
• Allows one mesh to be
placed on top of another
– No need to morph
– No need to re-mesh
• Easy to setup and use!
Industrial Applications: Automotive
Industrial Applications: Aerospace
Industrial Applications: Marine
Industrial Applications: Process Industry
Using Overset Meshes
Documentation
• Extensive documentation and tutorials for overset meshing
Solution History
• Solution recording and replay
– Comparing results from different: geometries, physical
conditions, meshes, etc.
• Solution “snapshots” for steady runs
– Automatic recording for unsteady,
• Result animations
• Helps to manage data storage
– Store only the fields you need
– Data stored in a separate .simh file
• Multiple scenarios reviewed
within a single STAR-CCM+ Session
Applications of Solution History
Using Solution History
Results
Documentation
• Documentation and tutorial on how to use solution history
• Interface type for CHT analyses
– Allows for quick and reliable generation of
non-conformal interfaces
– Saves time at the surface preparation stage

Advancing Layer Mesher
• New volume meshing technology
• Allows the generation of very thick polyhedral
prism layers
– Helps capture thick boundary layers and shock waves
• Suitable for “floating”
bodies
– Body of interest not intersecting
with flow boundaries
STAR-CCM+ Co-Simulation
• Allows thermal coupling of one STAR-CCM+ simulation to another
• Easy to setup and run
– User starts two servers and connects them together
– STAR-CCM+ controls time step negotiation
– User chooses which simulation leads
– Automatic start and stop of coupled simulations
Using Co-Simulation
• New element type for modeling thin solids
using “shell” elements
– Simulation of in plane thermal conduction
– Single or multiple layers of shells
