When enabled, you can use GPU acceleration for AMG computations on linear systems with up to 5 coupled equations and computing requirements grow as the number of cells in the domain increase. AmgX can even use MPI to connect clusters of servers to solve very large problems that require dozens of GPUs. Fluent uses AmgX as its default linear solver, and it takes advantage of a CUDA-enabled GPU when it detects one.
We call the library AmgX (for AMG Accelerated). NVIDIA partnered with ANSYS to develop a high-performance, robust and scalable GPU-accelerated AMG library. Comments can be added in the file with a semicolon at the beginning of the line. Journal File contains sequence of ANSYS Fluent commands that are identical to those that you would type interactively. It is a file that the background job will create, which will contain the output that ANSYS Fluent would normally print to the screen (for example, the menu prompts and residual reports). specifies the name of the output file.specifies the name of the journal or input file.That is, for nprocs solver processes running on M machines using ngpgpus GPUs per machine, we must have: Note that the number of processes per machine must be equal on all machines and ngpgpus must be chosen such that the number of processes per machine is an integer multiple of ngpgpus. specifies the number of GPUs per machine/node available in parallel mode.specifies the total number of CPU processors across all machines/nodes.

Streamlines the Fluent workflow for generating a mesh from imported CAD. Provides a complete, single-window solution within Fluent. Easy-to-use, task-based meshing workflows and Mosaic technology - paired with Fluent’s proven solver - deliver superior results. With the new Fluent experience, novice or expert users can run fluids simulations, in less time and with less training than ever before. Fluent set a world supercomputing record by scaling to 172,000 cores.Īll users can get great CFD simulation results with Fluent Fluent spans an expansive range, including special models, with capabilities to model in-cylinder combustion, aero-acoustics, turbomachinery and multiphase systems.įluent also offers highly scalable, high-performance computing (HPC) to help solve complex, large-model computational fluid dynamics (CFD) simulations quickly and cost-effectively. These range from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing and from clean room design to wastewater treatment plants.
