This release will be interesting for you if you are running OpenFOAM on desktop computer with the AMD cards.

Features:
- OpenCL version of Conjugate Gradient, BiConjugate Gradient together with diagonal preconditioner.
- OpenCL version of Sparse Matrix-Vector Multiplication.

The performance has been tested on three cases: external flow simulation over a simplified model of a car Ahmedbody with 1.37M cells, and blood flow simulations through basiliary and caretoid arteries.

See the full report for details.
