This means for UGGrid and FoamGrid you can now specify a grid in such a format in the input file For UGGrid and FoamGrid you can specify a grid in such a format in the input file:
`Grid.File = mygrid.vtu` / `Grid.File = mygrid.vtp` and the associated data is available in the grid data object `Grid.File = mygrid.vtu` / `Grid.File = mygrid.vtp`. The associated data is then available in the grid data object.
- __Freeflow__: A second order approximation of the convective term of all navier-stokes based models is now available. - __Freeflow__: A second order approximation of the convective term of all navier-stokes based models is now available.
