Default pairCollision in IcoUncoupledKinematicParcelFoam crashes

Hi everybody,

I am trying to use the pairCollision model in IcoUncoupledKinematicParcelFoam in OpenFOAM 1706. However the simulation crashes and gives the following error message. It gives a floating point exception which may be due to the division of a very small quantity. How do I rectify the problem? Does it involve changing the code?

Thanks in advance
