      Hi, I'm using an academic license for Anys 2022 R2. I can start workbench, spaceclaim, mechanical, cfx and so on. But when I try to run fluent from a fluidflow block, it opens a window in fluent displaying the following.

      "

      Unable to connect to external socket: Error during socket creation

      Opening output file:"SolutionResult.xml"

      I know someone suggests to launch fluent outside workbench but I need to get it done in the integrated environment. What could be the cause of this?

      Thanks.

      Hi Carlo,

      Try running after turning off your firewall and virus scanner.

      Already done, nothing. It's not the problem.
