Hi foamers,

I would like to report a bug with regard to the pimple implementation in compressibleInterFoam and similar solvers.
Code:
#include "alphaEqnsSubCycle.H"
            // correct interface on first PIMPLE corrector
            if (pimple.corr() == 1)
            {
                interface.correct();
            }
should be replaced with
Code:
// correct interface on first PIMPLE corrector
            if (pimple.corr() == 1)
            {
                #include "alphaEqnsSubCycle.H"
                interface.correct();
            }
This way the number of iteration for updating interface is consistent with number of iteration for solving alphaEqn. In this case, they are only updated in the first pimple loop. I have tested both implementation that the second one is much much more stable.

Hope this helps.
