The latest Caedium release has a broad range of new features, enhancements, and bug fixes. The new release includes an array of topology-based operations that support a new hybrid modeling scenario where you can build your flow volume from a mixture of faceted and analytic (CAD) geometry. Also there are a selection of new ways to run simulations, with two cloud-based services using Windows Azure and an experimental GPU option for NVIDIA hardware.
New Features and Enhancements
- Topology Operations
- Connect faces, edges, and vertices [Builder] to create:
- Non-manifold geometry for multi-block meshes
- Zero-thickness (or double-sided) walls
- Stitch edges and faces to create hybrid faceted and analytic geometry models [Builder]
- Perform subtract and decompose Boolean operations with hybrid models - no longer limited to true geometry [Builder]
- Running Simulations
- Outsource simulations to cloud-based services [RANS Flow]:
- Cloud Burst: Windows HPC Server 2008 R2 SP2 'Burst to Azure'
- Cloud: Windows Azure
- Experiment with state-of-the-art GPU acceleration using CUDA on NVIDIA hardware [RANS Flow]
- Faceted Modeling
- Import COLLADA faceted geometry from Google SketchUp [Exchange]
- Extract feature edges from faceted models with a facet feature angle preference [Exchange]
- Create hybrid faceted and true geometry models using new topology operations [Builder]
- Infrastructure
- Perform more robust Boolean operations using OpenCascade 6.5.1 [Builder]
- Realize shorter startup times and improved overall performance with OpenFOAM® 2.0.x, especially on Windows with new MinGW-w64 compiler improvements [RANS Flow]
- See reduced simulation turnaround time with an optimized OpenFOAM mesh representation [RANS Flow]
- Miscellaneous
- Use new selection filters to easily select geometry based on a wide range of constraints
- Automate operations, such as export, during simulation updates using new telemetrics [RANS Flow|Transient]
- Create detailed geometry, mesh, and physics reports using the new Info tool [Builder]
Bug Fixes
- Trying to create a force monitor on a non-simulation volume face caused Caedium to crash [RANS Flow|Panel Flow]
- Trying to extract results on a non-simulation volume caused Caedium to crash [RANS Flow|Panel Flow]
- Residual monitor properties included erroneous 'geometry' property after restore [RANS Flow|Panel Flow]
- Trying to display an existing Color Map (e.g., p) did not automatically switch the view to that Color Map [RANS Flow|Panel Flow]
- Scaling geometry by zero corrupted model [Builder]
- Poor error message when trying to use faceted geometry in a subtract Boolean operation [Builder]
- Errors and warnings about corrupt geometry during Boolean operations on simple shapes [Builder]
- Clipping slider properties did not respond to arrow or page-up/down keys
- Clipping range did not update after creating new geometry [Builder]
- Toggling Freeze sometimes caused internal errors [RANS Flow|Transient]
- Symmetry boundary condition visualization was not scaled by base units [RANS Flow|Panel Flow]
- Corrupt view if a camera was saved with the camera focal point at the camera position
- Temporary directory name clashes when running 100s of Caedium instances
- Camera shake during animation [RANS Flow|Transient]
- ABL Ustar calculation missing for epsilon [RANS Flow]
- AMG solver hit maximum iteration limit due to absolute tolerance being too small [RANS Flow]
- Erroneous blank camera upon restore after deleting a camera immediately prior to save on Linux
- Trying to drag and drop a window tab near an edge of the application caused Caedium to crash on Ubuntu 11.04
- Menu bar was invisible if desktop was switched from Ubuntu (default Unity) to Ubuntu Classic on Ubuntu 11.04
- Graphics driver memory leak on Mac OS X GeForce 9400. Workaround is to switch off hardware-accelerated displayed lists using new preference: File->Preferences, Visualization->Hardware Acceleration
