Feel++ Data Files
Feel++ generates various files that are spread over various directories. For this tutorial, it would be beneficial to check the content of these files to familiarize yourself with Feel++.
1. Environment variables
The environment variable FEELPP_REPOSITORY define the root directory where the simulation results will be stored.
By default they are set to $HOME/feel.
If you want to change the root directory where the results are stored, define e.g. FEELPP_REPOSITORY.
in Feel++ docker images, such as feel/feelpp, it points to /feel.
|
For running,
docker run -it -v $HOME/feel:/feel feelpp/feelppshould get you this output
feelpp@50381de2bd23:~$and here is the result of echo $FEELPP_REPOSITORY in the docker image
feelpp@50381de2bd23:~$ echo $FEELPP_REPOSITORY
/feel2. Results
Results of Feel++ simulations are stored in $FEELPP_REPOSITORY/feel/<your_app_name>/ or in a sub-directory.
The name of the directory is np_<num> where num is the number of processors used by the numerical simulation.
2.1. Logfiles
Feel++ uses Google Glog to generate logfiles.
They are stored in np_<num>/logs.
By default, only the master MPI process produces a logfile.
This can be changed using the option:
Option |
Description |
Default value |
disable_log |
Disable logfile generation |
false |
log_level_process |
log level: 2 enable logging for all processes, 1 enable only for master 0 disable for all processes |
