Energy definition: A conformal immersion : is minimal if and only if it is a critical point of the Dirichlet energy for all compactly supported variations, or equivalently if any point has a neighbourhood with least energy relative to its boundary. This definition ties minimal surfaces to harmonic functions and potential theory.
If flow across the boundary is zero: . Normal velocities are set to zero Scalar flux across the boundary is zero: . In this type of situations values of properties just adjacent to the solution domain are taken as values at the nearest node just inside the domain.
Showing wall boundary condition. The most common boundary that comes upon in confined fluid flow problems is the wall of the conduit. The appropriate requirement is called the no-slip boundary condition, wherein the normal component of velocity is fixed at zero, and the tangential component is set equal to the velocity of the wall.

In image processing, the free boundary condition is the convention used when applying a convolution kernel to a digital image in which pixel locations that lie outside the image boundaries are interpreted as having a value of zero.
The form of this boundary condition is an example of a Dirichlet boundary condition. In the majority of fluid flows relevant to fluids engineering, the no-slip condition is generally utilised at solid boundaries. [2] This condition often fails for systems which exhibit non-Newtonian behaviour. Fluids which this condition fails includes common ...
Frame rate, most commonly expressed in frames per second or FPS, is typically the frequency (rate) at which consecutive images are captured or displayed. This definition applies to film and video cameras , computer animation , and motion capture systems.
A measure of the rendering speed of a video game's graphics, typically in frames per second (FPS). frame-perfect An action that must be performed within a single frame for perfect execution. free look 1. To be able to look around the map freely, usually limited by typical mechanics of the game such as the boundaries of the game world. This is ...
If the boundary of Ω is C k for k ≥ 2 (see Differentiability classes) then d is C k on points sufficiently close to the boundary of Ω. [3] In particular, on the boundary f satisfies = (), where N is the inward normal vector field. The signed distance function is thus a differentiable extension of the normal vector field.
