I have followed the "Linux_Installation_Guide for Ansys195". The files .hosts, machines and hosts195.ans are OK!
Both machines have Selinux and Firewalld desactivated.
I have also setup ssh without password.
The installation folder are shared with NFS and the network is Infiniband Mellanox (100 Gb/s)
Could you please help us?. Thanks.!!..July 9, 2021 at 12:50 pmGeorge KarnosAnsys EmployeeCan you verify that all of the prerequisites are installed?
