Hello everyone：
I encountered an error in post-processing. When I used post-processing to convert post.out file to the file used in tecplot, the following error occurred:

error: internal error: cannot close polygon

May I ask what the reason is？ How to solve it?

Hello Tianyuan,

It points to the possibility of your post* files being corrupted. Is it just one or two files, or all post the files? For the former, please verify there were no intersections in the simulation when the faulty post files were written out. If is it giving the error for all post files, please ensure you're using the latest post_convert utility and preferably a more recent version of the CONVERGE solver.

If you continue to face issues, please get in touch with support@convergecfd.com. Please use your official email for all correspondence with Convergent Science. Please mention your issues and add the cfd-online thread, as reference.

Sincerely,
