Abstract: A computer-implemented method for simulating fluid flow using a lattice Boltzmann (LB) approach that includes assigning values for the wall shear stress on a per-facet (e.g., per-surfel) basis based on whether the fluid flow is laminar or turbulent is described herein.

Abstract: A door wrap has an inner and outer face. The outer face displays a main decoration and can have a main message zone. Additional components can include: a plurality of cut-outs, a plurality of attachable art pieces, and a door attachment means. The inner face faces towards an outer surface of a door and so is itself generally not visible when mounted. The inner face of the door wrap can also include second main decorations, main message zones, and attachable art pieces. The door attachment means can be a grommet attachment in each of the four corners and each including an elastic cord that can be wrapped over the corner of the door to secure the door wrap. Cut-outs can be scored so that a user can easily remove that portion of the door wrap to allow a door handle, etc. to protrude therethrough.

Abstract: A method for simulating a fluid flow that includes a laminar to turbulent boundary layer transition on a computer, the method comprising: for one or more locations on or near a boundary surface: performing a first calculation where a local boundary layer is taken to be a laminar boundary layer; performing a second calculation where the local boundary layer is taken to be a turbulent boundary layer; comparing a result from the first calculation to a result from the second calculation; and based on the comparing, selecting the result of the first calculation or the result of the second calculation; and inputting the selected result for the one or more locations into a simulation of activity of a fluid in a volume comprising the boundary surface.
