      Answer: There may be a number of reasons for this, which come down to the MPI processes not being able to talk to each other. Please make sure to allow mpid, mpirun, cx*.exe and fl*.exe from the firewalls. Additionally, if running Hyper-V on Windows 10, try removing that feature in the Turn On/Off Features section of the windows control panel, reboot, and try Fluent again.
