ANSYS Licensing

IT Services funds some Academic licences, but these do not provide all of the facilities in the whole range of Ansys packages. To see which features are available on these licenses, visit the Ansys Academic Products page; the IT Services' license covers products in the ANSYS Academic Research CFD and the ANSYS Academic Research HPC groups. Any additional features would have to be funded by the research groups who need to use them; contact the IT Service Desk if this is required.

Known Problems and Limitations

Ansys does not support remote display of some graphics, including CFX_Pre and CFD_Post, to a PC using Exceed3D.
