STAR-CCM+ Changes the Game, Again!

Overset Meshes A paradigm shift in how engineering simulation is carried out

Cuts down the entire analysis workflow Required when simulating bodies with extreme ranges of motion Easily execute parametric design studies

Solution History Designed to review, explore and interrogate the entire solution space

A collaborative environment Easily Compare and communicate design changes Animate transient data sets

Indirect Mapped Interfaces Drastically eases and shortens the set-up time for CHT

No need for geometric imprinting Allows for non-conformal fluid/solid interfaces Easily change designs

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!
