Warning for pv python code in rans test
test_pipe_laufer compiles with the following warning under g++7
/home/timok/dumux-course/dumux/test/freeflow/rans/test_pipe_laufer.cc: In function 'int main(int, char**)': /home/timok/dumux-course/dumux/test/freeflow/rans/test_pipe_laufer.cc:227:15: warning: ignoring return value of 'int system(const char*)', declared with attribute warn_unused_result [-Wunused-result] system(syscom.c_str()); ~~~~~~^~~~~~~~~~~~~~~~
looks like the result of the system call shouldn't be ignored. Why do we need the system call at all? Can't we have CMake to executing the post processing script (if it's for testing)? Otherwise just leave it to the user if he wants to execute the post processing? If you call it from C++ code there is also a paraview C++ API for that.
