Hi Everyone,

I'm getting the following error when running MPPICFoam in serial using the Implicit packing model (HarrisCrighton particle stress model).

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigSegv::sigHandler(int) at ??:?
#2 ? in "/lib/x86_64-linux-gnu/libc.so.6"

#10 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"
#11 ? at ??:?

I'm using the following setting in kinematic cloud properties

implicitCoeffs
{
alphaMin 0.0001;
rhoMin 1000;
applyGravity true;
particleStressModel
{
type HarrisCrighton;
alphaPacked 0.65;
pSolid 100;
beta 3;
eps 1.0e-2;
}
}

Psolid and beta values were taken from Snider 1998. The system is a liquid-solid system.

I gone through the velocityCorrection function but I have no idea what to look for.

Thanks in advance for you help.

I think problems were the empty boundary conditions, which don't seem to work with the velocity correction function.

Changing them to slip for velocity and zerogradient for pressure solves the problem.
