Logging

---

Singleton class for thread-safe logging.

The Logger class can be used to set the verbosity of the program. The verbosity levels are:

Code	Description
ERROR	Log errors only
WARNING	Log warnings
INFO	Log information (e.g. remaining time)
TIMING	Log timing results for the different methods
INTERMEDIATE	Save intermediate results (disk meshes) during the process
DEBUG	Debug

Example usage: Set the log level of the current program to INTERMEDIATE

C++

ps::Logger::setLogLevel(ps::LogLevel::INTERMEDIATE);

Python

vps.Logger.setLogLevel(vps.LogLevel.INTERMEDIATE)

Plasma etch diagnostics

At INFO verbosity or higher, the plasma models based on PlasmaEtching (including SF6/O2, HBr/O2, and SF6/C4F8) and FluorocarbonEtching report the normalized chemical, ion-enhanced, and sputtering contributions at the end of a process. These are fractions of accumulated rate contributions, not rates in length/time. The plasma base models additionally report substrate etch depth in the configured length unit.

At INTERMEDIATE verbosity, flux processes write disk meshes containing available flux, coverage, and surface-data arrays in cell data. Set the output directory with process.setIntermediateOutputPath(...). Source flux and surface-emitted/desorption flux are distinct fields; the latter use the _surface suffix.
