Hello.
During the simulation, the message as the attached picture is being output.
I'd like to ask you to solve this problem.

Currently we simulate a total of 3600 degrees. Note that it rotates 720 degrees in one cycle.
However, during the simulations, the simulation was paused when a message related to the seal was output at 2836 degrees.
Depending on the settings, the same message was also output at 676 degrees or at different angles.

We would like to know the causes and solutions of these messages.

Greetings,

Looks like your simulation is currently plagued with bad sealing points. Please recheck your seals to ensure that they are constructed properly. While there can be different reasons for this message, this error is usually seen when you have coarse sealing edges. The error message displayed prints out the location of these points. Please use the Animation tool to move the geometry at the location of crash (676CA) and refine all edges near the locations displayed.

Looks like the issue arises cyclically(676, 2836(676+720*3)) and thus should be limited to a single position. The reason for the message being displayed at different angles is most likely due to different settings providing different time-steps and consequentially different changes in surface movement around this location.

It would also be helpful to ensure you have appropriate resolution near any small gaps present and time-steps taken are not large. If you still continue to face these issues, please forward your case setup to support@convergecfd.com . Please use your official email for all correspondence with Convergent Science. Please mention the issues you were facing and add my name, and the cfd-online thread, as reference.

Hope this helps,

Sincerely,

Thank you very much for your kind reply.
Let me ask you one more question.
I wonder if the point of the error message in the analysis is the coordinate point after rotation.
If so, can you tell me how to view the rotated model within the CONNECTIONE Studio screen?
I've checked the animation on the View Options bottom, but it's not working.

Greetings,

Yes, the location displayed in the log corresponds to the position at that particular rotation angle. Unless you're employing a UDF to move your boundaries, and as long as you have defined your boundary motion under the Case setup tree, you should be able to visualize the motion using the Animation tool under View Options. At times, depending on the machine's GPU, the correct rendering argument must be provided when launching CONVERGE STUDIO (commonly seen in Windows machines). Please try launching STUDIO through the command prompt/terminal with the -n argument to enable visualization of animations.
Ex . C:\User\bin> CONVERGE_Studio.exe -n

If the issue persists, even with a latest version of CONVERGE STUDIO, please contact support@convergecfd.com. You can also consider manually moving the boundaries using the Transform >Translate/Rotate operations in the Geometry dock to the location at that angle, mark the involved edges and fix them at their original positions.

Sincerely,

I sent my case setup files by e-mail.
I wanted to correct the error myself, but I couldn't because of some difficulty.
I would appreciate it if you could help me.
