      Hi everyone, When I want to initialize a .cas setup, the fluent console give me this message:

      ==============================================================================

      Node 37: Process 9984: Received signal SIGSEGV.

      Hello,

      Could you please provide more information on what you are modeling? When does this error come up and does it show any text above this?

      Hello,

      I am modeling a complex industrial furnace in a steady state regime.
      When I open the case, this appears:

      ----------------------------------------------------------------------------

      ....
      bandwidth reduction using Reverse Cuthill-McKee: 413193/25410 = 16.261
      Info: The mesh contains elements that are invalid or of poor quality.
       
            A different numerical scheme will be applied to these elements,
            which may affect the quality of the solution. It is recommended
            that you consider removing the invalid and poor quality elements
            in the mesh.
       
            For more information on the invalid and poor quality elements,
            please use the following TUI commands:
       
            /mesh/check
            /mesh/repair-improve/report-poor-elements.
           materials,
           interface,
           domains,
      mixture
           zones,
      ...... all zones loaded,
      Done.

      ---------------------------------------------------------

      When I apply all the BC's and I click on initialization, this appears:

      ==============================================================================

      If the solver is flagging corrupt cells you may find fixing the mesh will remove the issue. The error is likely linked to the solver being unable to process data in some cells.
