Letâs take a look at some answers: 1  Architecture roles are generally differentiated by some level of solution-specific expertise in one area or another. 2  This could involve methodology, toolsets, skill sets or even industry domain knowledge.
Definition. A vector field on two (or three) dimensional space is a function that assigns to each point (or) a two (or three dimensional) vector given by (or). That may not make a lot of sense, but most people do know what a vector field is, or at least theyâve seen a sketch of a vector field.
The divergence of a vector field , denoted or (the notation used in this work), is defined by a limit of the surface integral. (1) where the surface integral gives the value of integrated over a closed infinitesimal boundary surface surrounding a volume element , which is taken to size zero using a limiting process. The divergence of a vector field is therefore a scalar field. If , then the field is said to be a divergenceless field. The symbol is variously known as nabla or del.. The physical significance of the divergence of a vector field is the rate at which density exits a given region of space.
