Hello Sam,

CHOLMOD usually throws this error when the boundary conditions are
improperly defined (hence the not positive definite). But it might also
throw this error if the time step is too large or if your packing has
exploded.

One way or the other, there is no way to know which problem is yours
since you have simply posted the error and you have not posted a minimal
working example [1].

Cheers,
