Case works on Single Core, but not Multi Core

Hello,

I have an OpenFOAM case which runs perfectly fine on a single processor, yet always seems to crash at the "Solve" portion with multicore processing.

I'm using my own implementation of fsiFoam, and was wondering if anyone has encountered a similar problem?

Code:

    for (label i=0; i<2; i++)

    {

        Foam::solve

        (

            fvm::laplacian

            (

                diffusivityPtr_->operator()(),

                cellMotionU_,

                "laplacian(diffusivity,cellMotionU)"

            )

        );

    }
