After update to v4.0.0 from 3.2.3, I start to run the test case downloaded along with the new version. The rans cases such as Rae2822, m6 are fine. But when I come to optimization_rans/steady_rae2822 or steady_oneram6, the program gets stuck as the picture shows.
Does anyone know the reason? How to solve it?
By the way, everything was fine when I using v3.2.3 on this cluster.ImageUploadedByCFD Online Forum1438308504.932654.jpgImageUploadedByCFD Online Forum1438308521.215181.jpg

Do you mean that it hangs and does not complete the simulations? There will be log files for individual steps of the optimization generated in sub-folders. There should be a DESIGNS/DNS_001/DIRECT/log.direct generated. By running "tail DESIGNS/DSN_001/DIRECT/log.direct" you should be able to see the running solution. (Apologies if the file names are not verbatim)
Output will only be generated to the screen at the end of each major iteration, and every iteration (line searches included) will be output to a history file as well as the individual DSN_* folders.

Yes, it is really as you said that there is a log file. Thanks hlk!
