  Hi, I am new to Ansys and trying out this tutorial from YouTube on the 2023 R1 version (CFX fluid). I run into these errors: (I uninstalled Ansys and re-installed it but the same errors persist, I attempted every solution I could find on the all-knowing Oracle, Google but to no avail)
  The ANSYS CFX solver exited with return code 1.
  Update failed for the Solution component in Fluid Flow (CFX). The solver failed with a non-zero exit code of : 2
  I've put the tilde in the place of my license ID

  | Checking for Isolated Fluid Regions |
  +--------------------------------------------------------------------+
  2 isolated fluid regions were found in domain Default Domain
  If the isolated regions do not have the pressure level set either
  by the boundary conditions or using a reference pressure equation,
  you may encounter severe robustness problems.
  This situation may have arisen because a domain interface was not
  properly defined during problem setup. Please carefully check
  the setup.
  The solver will stop now and write a results file. The isolated
  regions can be visualised in CFX Post by making plots of the
  variable "Isolated Volumes".
  If you are sure that the pressure level is set in each isolated
  fluid region then you can force the solver to turn off this check
  by setting the expert parameter "check isolated regions = f".
