Based on the peer review, selected contributors will also be invited to contribute full papers to a Special Issue in the journal “Computers & Fluids”. Criteria for selection are contributions that focus on (a) new methods/models (OpenFOAM being the framework) or (b) physical analysis (based on OpenFOAM simulations, with the usual validation level and new physical insights) or (c) pure validation of existing methods in OpenFOAM according the policy of Computers & Fluids for benchmark solutions.
