Computational Fluid Dynamic (CFD) software requires the geometry in the form of a mesh as an input. The mesh is generated based on an electronic technical drawing. In our case we used Salome for both tasks, namely for drawing the geometrical objects as well as the isolation of the fluid bo...

On the other hand, Mesh Adaption—Dynamic Remeshing and Key Frame Remeshing rely on the deformation of the grid: the operation of the machine is intrinsically evaluated by updating the cells close to the wall. Indeed, this includes a term for the boundary displacement that is plugged in as ...

18, 24 This method is also known for the hydrodynamic theory of contact angles, where local slip is allowed to avoid a mathematical singularity at the contact line due to the abrupt change of material properties at the interphase.2 In principle, the tolerance of local slip leads to a ...
