Description

Hello,

It seems that the field "ustar" is not written in the auxiliary restart file. Thus, when doing a restart, it is zero until the first estimation in condli. [https://www.code-saturne.org/forum/viewtopic.php?f=2&t=2641](url)

Regards,
Cédric

Research direction

Trace the auxiliary restart-file handling for the ustar field and the first restart step, then inspect the condli entry point mentioned in the report. Reproduce a restart and verify that ustar is restored from the auxiliary file rather than remaining zero until condli estimates it.
