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

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

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:

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

Node 14: Process 13064: Received signal SIGSEGV.

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.
