Caedium v4 Sneak Peek: Centrifugal Compressor Passage CFD Simulation
We are still working on the next version of Caedium and thought it was time to share another update on Caedium v4 progress. This sneak peek highlights the new Caedium cyclic boundary condition along with other enhanced geometry tools that will enable CFD simulations of an idealized axisymmetric centrifugal compressor blade passage for instance.
New Cyclic Boundary Condition
The new cyclic boundary condition in Caedium v4 will offer significant memory and turnaround time savings, given that you only need to simulate the axisymmetric portion of your model. For the example of the blade passage shown below you will only need to simulate a tenth of the full model due to the 36 degree axisymmetric nature of the geometry.
Improved Connect Tool
With an improved tolerance algorithm used by the Connect tool in Caedium v4, it will be significantly easier to connect faces, edges, and vertices to form watertight volumes and also to create multi-block regions for hexahedra meshing. The blade passage example shown below incorporates 6 blocks that represent the flow domain meshed with the Caedium hexahedra meshing tool.
Improved Double-Sided Face Tool
Further improvements to the 2-Sided tool in Caedium v4 will make it easier to deal with complex topology connections to multiple volumes and non-manifold edges. In the example below the idealized blade in the passage is represented as a double-sided face.
