Workflow automation and ease of use continue to be a focus of STAR-CCM+ v11.02. Reference geometries such as points, planes, axes and coordinate systems can now be created on a component in 3D-CAD. These entities will remain ‘pinned’ to the geometry they are created from, making it easy to build more complex geometries and enabling automated design exploration.

Local surface remeshing allows for remeshing only selected areas when changing mesh parameters or performing design changes, reducing surface mesh generation time up to an order of magnitude and a key enabler of efficient design space exploration.

STAR-CCM+ v10.06 brings a new and significantly enhanced interface for the Manual Surface Repair Tool, greatly increasing usability for both the experienced and new user. The new interface provides an easier to use and simpler environment for performing manual repair of geometries and surface meshes. Experienced users will find that repairing geometries requires less clicks and makes everything easier to identify and locate. New users will find the new interface easy to navigate and learn.

In the upcoming release of STAR-CCM+, v10.04, we have added two new features to significantly increase the flexibility of the CAD-clients as well as add a new dimension to the transfer. CAD-clients now allow import of reference planes and coordinate systems. These entities may be used within STAR-CCM+ for a range of tasks. CAD-clients now enables direct import of CAD files as well, opening the door to insert a bi-directional link into a template or existing sim file without the need to fire up your CAD package.

James Clement tries to capture "the big one".One warm July morning buddy of mine and I decided that we needed to hit the lakes and go catch "the big one". We headed out just as dawn broke so we can find that big old bass that I knew was hidden somewhere in our favorite spot. Once we got the boat in the water it is about a 15 minute ride across the lake over to the spot where our fish was bound to be. So a cup of coffee in hand we sped off across the lake, during that time one’s mind always tends to wander and apparently mine wanders back to meshing. Looking across the still lake nothing much is going on but behind the boat is a whole different story; the propeller is stirring up quite a bit of turbulence and the hull is producing a massive wake, this is where the action is. So I ask to myself, what kind of tools would our users need in order to build meshes automatically in order to capture this type of phenomena? A tool that would allow efficient meshes and could give accurate answers with a minimal cells count. STAR-CCM+ v10.02 meshing operation allows users to refine wake zones in both the polyhedral and the trim meshers as well as give wake a draft angle so that the refinement zone expands as it moves away from the model.

2D simulation is a great way to test out designs and boundary conditions, personally I use it all the time when I am setting up a complex case for the first time or just playing with a new feature.
Historically in STAR-CCM+ there wasn’t a pipelined way to build and run 2D meshes, but now with version 9.06 there are two new features that will put that problem to rest.

2D Mesher in STAR-CCM+

So, show of hands, who has wrapped a surface and asked: "This surface is clean, why do I have to wrap it?".

The good news is that a new method introduced in STAR-CCM+ v9.06 will allow you to selectively wrap dirty surfaces, while preserving those that are clean.

In an effort to make STAR-CCM+ even faster on a broader range of problem types STAR-CCM+ v9.04 (which is released next week) will offer Concurrent Per-Part Meshing (which is a bit of a mouth full, so we'll call it CCPM instead).

Now, I'm sure you're asking yourself, ‘What’s the difference between CPPM and regular parallel meshing?’
