empty monitoring files

Post by lb_yuan »

Hello,

Recently, I found a tricky issue when using Code_Saturne v5.0.8 that the monitoring files are not updated at all since they are generated at the beginning of the simulation. This seems not to happen on some of the machines even with exactly the same setups. Does anyone encounter with the same issue?

Kind regards,
Bo

Hello,

This is usually due to buffering issues, and may depend on the filesystem you are running on (i.e. you can expect more buffering on clusters, to avoid slowing down the code due to too much I/O synchronization).

You can normally force buffering from one time step to another by running 'touch control_file' (i.e. creating an empty control_file) in the execution directory, or search for "flush_defaults" here: https://www.code-saturne.org/cms/sites/ ... ocess.html

Regards,

Yvan
