CFD-Post won't plot or display the results
 

Hi all,

I have completed an FSI problem successfully in ANSYS 18.1 (After about 12 hours!). This was not the first time I do such an analysis. However, this time was different.

The geometry is very simple - it is just a flexible tube with a fluid inside! After completing the analysis, the CFD post won't display (plot) the results even though there is no error showing in the Project Schematic platform. Please see the attached pictures.
I refreshed everything, but nothing works.
Now, I tried to read a time course data from a point that I created, but this error shows up. It is in the third picture. And the text says:
.................................................. ...............................
The application has encountered an unexpected problem and will now terminate:
Aborting due to unexpected error:
socketError:
RemoteEngineProtocol::receiveTran
Stat-Communication error:
Unexpected end of transmission from engine, expected status code.
Please report this error, along with the circumstances in which it occurred.
The following information may be useful to CFX support:
Unexpected error: Abortion due to unexpected error:
socketError:
RemoteEngineProtocol::receiveTran
Stat-Communication error:
Unexpected end of transmission from engine, expected status code.

Does anyone know what is happening? Thank you.
