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" #3 Foam::PackingModels::Implicit<Foam::MPPICCloud<Foa m::KinematicCloud<Foam::Cloud<Foam::MPPICParcel<Fo am::KinematicParcel<Foam:article> > > > > >::velocityCorrection(Foam::MPPICParcel<Foam::Kine maticParcel<Foam:article> >&, double) const at ??:? #4 ? at ??:? #5 ? at ??:? #6 ? at ??:? #7 ? at ??:? #8 ? at ??:? #9 ? at ??:? #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. Victor |

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. |
