ANSYS, Inc. Release Notes
New features and enhancements to ANSYS CFX and CFD-Post introduced in Release 13.0 are highlighted in this section.
The operation of ANSYS CFX in ANSYS Workbench is described in ANSYS CFX in ANSYS Workbench.
Solids can now be included in porous domains to model conjugate heat transfer and/or the transfer of Additional Variables.
There is a new six-degrees-of-freedom (6DOF) Rigid Body feature that enables you to model a rigid body as a collection of 2D wall boundaries. You can also make an immersed solid act like a rigid body. In both cases, fluid forces and specified external forces/torques act on the rigid body. Each approach has its advantages and disadvantages:
When modeling a rigid body as a collection of wall boundaries, wall boundaries are sharply resolved, but the mesh must be distorted to follow the boundary motion.
When modeling an immersed solid as a rigid body, the mesh undergoes no distortion but the wall boundaries are not sharply resolved.
ANSYS CFX now works with Remote Solve Manager (RSM).
For this release, ANSYS CFX also introduces the following features:
Particle Tracking: Particle Source Bounding
Turbulence Bounded CDS
Boundary Condition Radial Equilibrium
Particle Tracking Sommerfeld Virtual Wall
Soave Redlich Kwong Equation of State
RIF Extensions in CFX-Pre
ANSYS CFX documentation now appears in the ANSYS Help Viewer, which makes it easier for you to find information about other ANSYS products that you can use with ANSYS CFX.
There have been numerous incremental improvements to the organization and content of the documentation to improve clarity and usability. In addition there is a new tutorial: Modeling a Buoy using the CFX Rigid Body Solver in the CFX Tutorials.
This section highlights the new features supported in this release of CFX-Pre.
Algorithmic changes have been made to the way render information for objects, such as color and shading, is stored and processed by CFX-Pre. These changes have been shown to give significant speed improvements for model manipulation where large numbers of objects are visible in the viewer window.
Stereo Viewing capabilities, previously available only in CFD-Post, are now also available in CFX-Pre. This allows full stereo-viewing capability for appropriate hardware. This feature can be enabled from the Viewer branch of the Edit > Options menu.
Several improvements have been made to the way Automatic Domain Interfaces are created and checked inside CFX-Pre. This includes more robust checking of multiply-connected domains and problem regions relating to many-to-one connections.
The following element types can now also be imported from ANSYS cdb files into CFX-Pre:
Element Type 28 (Shear/Twist Panel), KEYOPT (0)
Element Type 212 (2D 4-Node Coupled Pore-Pressure Mechanical Solid), KEYOPT (0)
Element Type 213 (2D 8-Node Coupled Pore-Pressure Mechanical Solid), KEYOPT (0)
Element Type 215 (3D 8-Node Coupled Pore-Pressure Mechanical Solid), KEYOPT (0)
Element Type 216 (2D 20-Node Coupled Pore-Pressure Mechanical Solid), KEYOPT (0)
Element Type 217 (2D 10-Node Coupled Pore-Pressure Mechanical Solid), KEYOPT (0)
Element Type 233 (2D 8-Node Electromagnetic Solid), KEYOPT (0)
Element Type 236 (3D 20-Node Electromagnetic Solid), KEYOPT (0)
Element Type 237 (3D 10-Node Electromagnetic Solid), KEYOPT (0)
Element Type 241 (2D Hydrostatic Fluid), KEYOPT (0)
Element Type 242 (3D Hydrostatic Fluid), KEYOPT (0)
Element Type 285 (3D 4-Node Tetrahedral Structural Solid with Nodal Properties), KEYOPT (0)
To obtain a full list of supported ANSYS element types, type the following at a command prompt
install_dir/v130/CFX/bin/ImportANSYS.exe -S
License server checking has been improved, leading to shorter waiting times for diagnostic messages, particularly when license servers are unavailable.
New features and enhancements to the CFX-Solver Manager introduced in Release 13.0 are highlighted in this section.
Plot lines of related residual quantities for solution of EMAG/MHD calculations (such as Electric Potential) now appear automatically in the CFX-Solver Manager under the Electromagnetism tab.
New features and enhancements to the CFX-Solver introduced in Release 13.0 are highlighted in this section.
This section highlights the new features supported in this release of the CFX-Solver.
Support for the individual specification of Turbulent Prandtl and Turbulent Schmidt numbers has been added. Support has also been added for specifying these as CEL expressions.
Volume Rendering
Volume Rendering enables you to visualize field variables throughout the entire domain by varying the transparency and color of the plot as a function of the variable value. For example, you can make realistic images of smoke and analyze how it spreads and how it affects visibility.
Chart
You can now position the chart legend on the chart area, in addition to the surrounding chart area where the axes are found.
Chart axis numbers can now be formatted in either standard or scientific notation.
Comparisons Mode
The automatic detection of the same mesh is much faster.
You can now tell CFD-Post that meshes are either same or different in the Case Comparison panel, which can make the comparison mode much faster.
Turbo Postprocessing
Hub-to-Shroud turbo line points can now be distributed based on mesh density.
Table
Table updates are much faster.
Stereo Viewer
Support is added for graphics display on typical stereo hardware.
ANSYS FLUENT Files
Particle tracks can now be exported from ANSYS FLUENT and post-processed in CFD-Post.
CFD-Post can now read interior face zones from ANSYS FLUENT files. Set this ability from the Edit > Options > CFD-Post > Files panel.
CFD-Post now performs more accurate interpolation inside concave polyhedra in ANSYS FLUENT files. This resolves issues with streamlines stopping in the middle of the domain when hitting a concave polyhedron.
CFD-Post can now perform more accurate (cell based) evaluation of user-defined variables.
