How to debug with valgrind
Using "valgrind"program help one to recognize memory errors. To debug with valgrind in command line while inside example directory execute following line
valgrind python cavity2D-incomstatic.py >debugtest.out
debug process for "cavity2D-incomstatic.py" is saved in "debugtest.out". various options of valgrind are accesable by this command
so this could be a usefull option for complete debug
valgrind --leak-check=full python cavity2D-incomstatic.py >debugtest.out
There are some cases in which valgrind gives "Conditional jump or move depends on uninitialised value(s)" message and the error origin is in some statements before. In this cases the "--track-origins=yes" can be very useful in finding the real source of error.
valgrind --track-origins=yes python cavity2D-incomstatic.py >debugtest.out
If instead of the command line, the command is written in "emacs" reading the file is much easier.
