All computations on this page have been carried out with solvers in my AMROC framework using routines from the Virtual Test Facility. Note, however, that AMROC has progressed significantly beyond the currently released version V2.0 in terms of scalability, lattice Boltzmann and multiphase solvers, coupling to structural solvers, etc. A new release V3.0 is planned. In the meantime, please send me email to inquire about solvers that are not available from the VTF download page.
