We certified the specified version of ANSYS on the following Linux distributions. In most cases our software will run on newer versions of these distributions, especially patch-level updates. However, we are aware of some problems that occur with different levels of the Linux libraries, such as glibc. For the best performance, we recommend that you run ANSYS on a certified level of the operation system.
