Moving mesh capability in CCM+
Hi
Does anybody know what moving mesh capability is available in the latest version of CCM+? R |
Re: Moving mesh capability in CCM+
you still have sliding grid with rigid body motion: translation or rotation.

Re: Moving mesh capability in CCM+
Star CCM+ currently has no moving mesh capabilities but it is being updated evry few of months

Re: Moving mesh capability in CCM+
Goulash is right, Luke is wrong. There is rigid body (rotating) motion as well as complete domain motion for stuff like sloshing etc

Sorry. My bad...

Re: Moving mesh capability in CCM+
I've been currently using Star CCM+'s ability to replace a mesh and map the solution to account for motion.
I created a VBA macro for Solidworks that generated all of my geometries automatically based on parameters of the problem. Then I created a java macro that would open each one of the geometries in Star CCM+, create the mesh, and export the mesh. Next I created a java macro that would first define paramaters of the problem (such as times step, number of iterations, etc.), iterate on one mesh, and then replace it with a new mesh for the next timestep. For the problem I was solving the flow was caused by the motion of one flat plate relative to a stationary plate, so to account for this a field function was created that would define a volumetric source term based at each timestep. I have compared my results to a first-order analytical solution, and the results agree very well. Jayson Martinez |

Also, in the Java API there is something called Star Morpher, which makes references to moving meshes, but is not very well documented. If anybody has any idea how to use this I would be very interested in finding out how.
