Ansys License
License Server
The Ansys licenses are stored on two license servers. On one the Ansys Academic Research licenses can be found, on the other the Ansys Academic Teaching licenses.
The teaching licenses are available, free of charge, for students on the RWTH High Performance Computing cluster.
The research licenses can be purchased by institutes of RWTH Aachen University in the Software-Shop.
The access to the Ansys Research licenses is restricted to IP adress ranges on the license server and on user identifications on the RWTH High Performance Computing cluster. If you have not done so yet please send these after the purchase of the software with your order confirmation to the IT-ServiceDesk.
Please note that you will, in addition to the installation of Ansys, have to install a local license server. It makes sure that your computer's IP address is transferred correctly to the license server and thereby facilitates the unlocking of licenses via IP ranges.

Licenses for GPU-based computations
If Ansys calculations are performed on GPUs, a larger number of Ansys Academic Research HPC licenses is generally required. GPU usage is licensed based on the number of streaming multiprocessors (SMs).
40 SMs are already included in the base license. An HPC increment is required for each additional SM.
This means that for a Fluent simulation using an NVIDIA H100 SXM5 version with 132 SMs, in addition to the "Ansys Academic Research Mechanical and CFD” license, 132 − 40 = 92 “Ansys Academic Research HPC” licenses are required.
