Thanks Matt! I have just signed up in the customer portal and found the description of silent mode installation of License Manager. Though I am having trouble to find out documentation for OPERATING it silent mode.nAnd about the issue of running Fluent on the Ubuntu client, I have gone through the list of pre-requested libraries and installed the missing ones except the following which are not available for Ubuntu at all:nlibfreebl3; libopenssl1; libz1nWhen launching Fluent there is still a problem which now seems to be relating to MPI. I am saying this because the selection of MPI mode in the Fluent launcher is leading into different symptoms. nThe console in Fluent is giving out the following error log for choosing MPI = [ Default ] :n*********n/ansys_inc/v202/fluent/fluent20.2.0/bin/fluent -r20.2.0 2ddp -pshmem -host -alnamd64 -t2 -mpi=intel -path/ansys_inc/v202/fluent -ssh -cx ASRC-CalSer01:38509:35817nStarting /ansys_inc/v202/fluent/fluent20.2.0/lnamd64/2ddp_host/fluent.20.2.0 host -cx ASRC-CalSer01:38509:35817 (list (rpsetvar (QUOTE parallel/function) fluent 2ddp -flux -node -alnamd64 -r20.2.0 -t2 -pshmem -mpi=intel -ssh) (rpsetvar (QUOTE parallel/rhost) ) (rpsetvar (QUOTE parallel/ruser) ) (rpsetvar (QUOTE parallel/nprocs_string) 2) (rpsetvar (QUOTE parallel/auto-spawn?) #t) (rpsetvar (QUOTE parallel/trace-level) 0) (rpsetvar (QUOTE parallel/remote-shell) 1) (rpsetvar (QUOTE parallel/path) /ansys_inc/v202/fluent) (rpsetvar (QUOTE parallel/hostsfile) ) )n       Welcome to ANSYS Fluent 2020 R2n       Copyright 1987-2020 ANSYS, Inc.
