请问Seast是否有Flow3D 8.2
What's New in FLOW-3D® Version 8.2
In addition to several new and useful physical models, the multi-block grid coupling has been significantly improved and one of FLOW-3D®’s strengths, the VOF method for tracking fluid interfaces, has been enhanced. We’re calling it TruVOF®, because we feel our implementation is the truest form of that method there is.
And with Version 8.2, we’ve taken a big step forward in user-friendliness. Perhaps the most significant functional change for many users will be the new interactive, on-screen geometry and mesh creation capability we have built into the user interface.
What follows is a brief description of the key new features and changes to FLOW-3D® for Version 8.2.
New VOF advection model -- TruVOF®. A new semi-Lagrangian VOF advection method has been implemented. The new VOF advection model has enhanced the ability of FLOW-3D® to track fluid interfaces in complex 3D flows. Go here for more information.
Improved Multi-block coupling model. Stability, accuracy and efficiency of pressure-velocity coupling between mesh blocks has been greatly improved through the use of the Chimera multi-block method. The new method further widens the range of problems that can be tackled with FLOW-3D®, from large scale flows in civil engineering to casting to micro-electro-mechanical systems (MEMS). Go here for more information.
Improved Graphical User Interface. FLOW-3D® now offers users the ability to interactively create and modify geometry and meshes using the FlowVu OpenGL-based visualization program.
New Elastic-plastic stress model. A new elastic-plastic stress model has been developed for modeling materials having elastic properties. A yield stress may be defined to allow for plastic flow of these materials. Go here for more information.
New Electro-osmosis model. A new electro-osmosis model, using a GMRES-based solver, has been implemented. Go here for more information.
New Sand core blowing model. A brand-new model simulating the sand core blowing process has been developed Go here for more information.
New Two-Fluid model. A phase change has been added to the two-fluid model in the absence of free surface. Condensation/boiling can be initiated in situations when initially there is only vapor or fluid present.
New Implicit Shallow Water model. An implicit treatment of pressure forces has been added to the shallow water model. The addition eliminates the time-step stability limit associated with the explicit setting of the free surface pressure as a function of fluid depth and gravity.
New Individual Blade Effects. We have added a model for individual blade effects for fan-type rotating obstacles.
Improved Lost Foam Model. We have added a capability to have variable density foam patterns. Using a special scalar, the user can define how the foam density deviates from an average: a zero value of the scalar means no deviation. Go here for more information.
New Visualization Capabilities. An option has been added to the post-processor to allow the generation of iso-surfaces that are suitable for symmetry reflection for both Cartesian and cylindrical geometries. Users can also display particle data at the same time as fluid and obstacle iso-surfaces.
Improved Post-Processing. We have made the post-processor more robust by allowing it to continue data extraction when a requested variable is not found in the results file. This is even more useful for restart calculations. FLOW-VU has been made significantly more efficient in both speed and memory use. And the file size limit for results files has been increased on all platforms to up to 1,280 gigabytes (1.28 terabytes). |
