Visual-Environment Highlight of Visual-CFD: Multiphase Flow
In fluid mechanics, multiphase flow is the simultaneous flow of materials with two or more thermodynamic phases. These phases may consist of one chemical component (e.g. flow of water and water vapour), or several different chemical components (e.g. flow of oil and...

Visual-Environment Highlight of Visual-CFD: Adjoint Optimisation
The adjoint method has long been considered as the tool of choice for gradient-based optimisation in computational fluid dynamics (CFD). The adjoint method, allows computation of sensitivities, i.e. the derivative of the objective function with respect to the design...

Visual-Environment Highlight of Visual-CFD: Reacting Species
Modelling reactive systems is numerically expensive since the non-linear reaction kinetics leads to stiff-ODE systems in the species and energy conservation equations. Special solution algorithms, capable of handling these stiff systems of equations, different ODE...

Visual-Environment Highlight of Visual-Seat: Foam Blocks Positioning
When assembling the different components of the seat, it may happen that the foam at rest is intersecting the frame and/or the suspensions. In order to remove those intersections, a simulation-based technique had been implemented previously by applying surface pressure...
