New Features in Edge 4.0

A brief summary of the most important of the new developments in Edge, version 4.0, is given below.

Adjoint Solver
The adjoint solution to an existing Euler solution for parameterized surfaces with respect to, for example drag, still maintaning constant lift can now be computed. The gradient in design space can also be collected. The adjoint solver is also parallelized.

Y-plus Adaption
Functionality to redefine the prismatic layer distribution in a mesh is added.

Wall Functions
A wall function approach denoted “universal wall boundary conditions” is implemented in which y+ in the first layer of nodes very well can be within the boundary log layer, i.e. y+ > 30, and where a finite velocity component is specified strongly. In principle any value of y+ in the first layer is accepted. As the grid is refined the wall functions boundary conditions approach the standard no-slip conditions.

Aeroelasticity
Fluid/structure interaction fully parallelized.

Paraview Support
Conversion tools to port data to the EnSight Gold format are now available. This format can, apart from EnSight, be read by the Open Source Visualization Project Paraview.
