The dispersion model calls the member function epsilon() of the kOmegaSST model. So the error might result from a k or an omega close to zero. Temporarily I fixed this issue by adding a max operator max(epsilon, SMALL) to the dispersion model. The exception is only thrown when running OpenFOAM in parallel. | ||||
