Hello,

I have a steady-state simulation that worked just fine. Then I changed one of the boundary conditions from velocity inlet to pressure inlet and re-solved. The solution converged just fine, but immediately after solving I get the error, as if Fluent tries to do something new after solving. I have no idea why simply changing boundary conditions and re-solving leads to this error.  Here is a screenshot.

 

 

As I said, this error shows up before I try to do anything with the solution.   Note the solver says solution has converged.

What steps can I take to get rid of this error?  It prevents me from updating the solution in WorkBench even though I have convergence according to the solver.

Did you have any commands used on 'velocity-inlet'? e.g. isousurface of mesh or contours or similar to that? 

It looks like Fluent is trying to display something from here and it not getting that zone.

Hello kkandade,

No.  I issued no commands.  That is what is so puzzling about this.  Anything else I should look for here?

[Keyur Kanade]

It must have something defined like report or contours etc. which Fluent is trying to update after solution is complete.

Can you delete cell 'C' in your workbench project, create a new 'Fluent' cell and connect to 'Mesh' cell. Set it up again from scratch and rerun. 

If the project is big, you can test on a simple cylinder case.

Regards,

Keyur

Hi everybody;

I got the same error after I set the outlet pressure for boundary conditions. Does anybody know how to fix it? 

Thanks.

have the same problem. seems like a bug

You changed a boundary type, that can cause contour objects to reset and that could then give that error. Check reports and all graphics objects that use that surface.
