Should I limit the pressure gradient when doing steady incompressible simulation with low-quality volume mesh?In other words, can I set the default gradient scheme as



gradSchemes
{
default cellLimited Gauss linear 1;
}
?


In this page, https://bugs.openfoam.org/view.php?id=1410#c3246, Henry suggested that the pressure gradient should NEVER be limited. But I am not sure the reason behind it.
