16.1. Activating the GPU Accelerator Capability
Following is the general procedure to use the GPU accelerator capability:
1.Before activating the GPU accelerator capability, you must have a
supported GPU card and at least one ANSYS HPC Pack license.
2.Open the Mechanical APDL Product Launcher.
Windows:
Start >Programs >ANSYS 13.0 >Mechanical APDL Product
Launcher
Linux:
launcher130
3.Select the correct environment and license.
4.Go to the High Performance Computing Setup tab. Select Use GPU
Accelerator Capability.
5.Alternatively, you can activate the GPU accelerator capability via the
-acc command line option:
ansys130 -acc nvidia
6.If working from the launcher, click Run to launch ANSYS.
7.Set up and run your analysis as you normally would.
With the GPU accelerator capability, the acceleration obtained by using the parallelism on the GPU hardware occurs only during the solution operations. Operational randomness and numerical round-off inherent to any parallel algorithm can cause slightly different results between runs on the same machine when using or not using the GPU hardware to accelerate the simulation.

16.2. Supported Analysis Types and Features
Some analysis types and features are not supported by the GPU accelerator capability. The following sections give general guidelines on what is and is not supported. These are not comprehensive lists, but represent major features and capabilities found in the ANSYS program.
The GPU accelerator capability is not supported when using Distributed ANSYS. 16.2.1. Supported Analysis Types
This section lists analysis capabilities that are supported by the GPU accelerator capability.
Supported Analysis Types
The following analysis types are supported and will use the GPU to accelerate the solution.
Static linear or nonlinear analyses that use the sparse, PCG, or JCG solver.
Buckling analyses using the Block Lanczos eigensolver.
Modal analyses using the Block Lanczos or PCG Lanczos eigensolver.
Full harmonic analyses using the sparse solver.
Full transient linear or nonlinear analyses using the sparse, PCG, or JCG
solver.
In situations where the analysis type is not supported by the GPU accelerator
