    Dear Developers,

    When I handle the code of example aorta3d, in the end of the function get results,
    there exists
    “if (sLattice.getStatistics().getMaxU()>0.3){
    …

    std::exit(0);
    “

    What does this mean? and what is the function of this? Thanks very much!

    That basically means that the simulation tuned close to unstable. In such cases the results are not really reliable. THerefore we add this code to stop the simulation.

    Best

    Dear Mathias,
    Thanks for you reply. How do we determine this threshold value, that is 0.3 here.
