Reducing the number of files in a plotfile directory

[wjwhit]

Greetings,

I am currently running an AMReX based code on an HPC system that has a relatively strict limitation on the number of files in my run directory - the size of the files is not an issue. Is there any way to reduce the number of files that compose each plotfile directory, ideally during runtime?

Thank you,
William

Call amrex::VisMF::SetNOutFiles(n), where n can be say 16. The default in amrex is 256.

Perfect, thank you!
