Before you begin your CFD analysis using the Fluent GPU Solver, careful consideration of the following issues will contribute significantly to the success of your modeling effort. Additionally, when planning a CFD project, be sure to take advantage of the customer support available to all Ansys Fluent users.
Many of the features available for the CPU-driven solution mode of Ansys Fluent outlined in the Fluent User's Guide are not yet supported by the Fluent GPU Solver. Your CFD analysis using the Fluent GPU Solver must adhere to the supported features and limitations as outlined in Features Supported by the Fluent GPU Solver and Fluent GPU Solver Limitations.
After you have determined the important features of the problem you want to solve perform the following basic procedural steps:
Define the modeling goals.
Specify one or multiple GPUs to be used with the GPU solver within the Fluent Launcher or within the command prompt, as outlined in Starting the Fluent GPU Solver.
Read in a 3D mesh or case file (with or without a corresponding data file) to represent the fluid domain. For information on reading a Fluent case file into the Fluent GPU Solver, see Reading Fluent Case Files Into the Fluent GPU Solver.
Set up the models, materials, cell zones, boundary properties, and report definitions.
The settings defined for your CFD analysis using the Fluent GPU Solver must adhere to the GPU solver supported features and limitations.
Set up calculation activities.
Compute the solution. For information on computing steady-state solutions and transient solutions see Performing Steady-State Calculations and Performing Time-Dependent Calculations, respectively.
Examine and save the results.
Consider revisions to the setup, if necessary.
