[WIN]CONVERGE Studio (流体动力学软件) 3.2 with Solvers 特别版

“In CONVERGE 3.0, we switched from partitioning the domain on blocks coarser than the solution grid to partitioning the solution grid directly,” says Keith Richards, co-owner of Convergent Science and one of the principal developers of CONVERGE. “This allows us to get a good load balance for any solution mesh, including those with very high levels of embedding, and means CONVERGE scales well even on thousands of cores.”

The way CONVERGE stores information during simulation runtime has also been modified in version 3.0, resulting in a greatly reduced memory footprint. Additionally, CONVERGE’s post-processor, Tecplot for CONVERGE, is more seamlessly integrated into the software, creating a smoother workflow for users.

CONVERGE 3.0 offers more flexibility in meshing than previous versions. With autonomous meshing, CONVERGE automatically generates an optimized Cartesian mesh at runtime. In 3.0, users can optionally incorporate an inlaid mesh in a region of the grid to obtain accurate results with fewer cells. Inlaid meshes can be aligned with the flow direction to reduce numerical viscosity, or users can refine the mesh in only one or two directions instead of all three. This allows users to accurately resolve boundary layers, for example, at a reduced computational cost by increasing mesh resolution only normal to the wall.

Among the new features in CONVERGE are two new combustion models. The thickened flame model for use in conjunction with LES (TFM-LES) is useful for simulations with large differences in length scales, like resolving the flame front in a boiler. The second new model, SAGE PDF, accounts for turbulence-chemistry interactions in flames modeled with RANS.

CONVERGE’s chemistry capabilities have also been enhanced in version 3.0. The SAGE detailed chemistry solver has seen significant speedup, especially for large reaction mechanisms, making CONVERGE one of the fastest chemistry solvers on the market. In addition, CONVERGE 3.0 includes numerous new chemistry tools, including new 0D chemical reactors, a new 1D flamespeed solver, and enhanced tools for manipulating chemical mechanisms.

CONVERGE is a revolutionary computational fluid dynamics (CFD) program thateliminates the grid generation bottleneck from the simulation process. CONVERGE wasdeveloped by engine simulation experts and is straightforward to use for both engine andnon-engine simulations. Unlike many CFD programs, CONVERGE automaticallygenerates a perfectly orthogonal, structured grid at runtimebased on simple, user-definedgrid control parameters. This grid generation method completely eliminates the need tomanually generate a grid. In addition, CONVERGE offers many other features to expeditethe setup process and to ensure that your simulations are as computationally efficient aspossible.
