==A==
;active level:The capsule of a model project currently selected in the Capsule Set pane and displayed in the Model Canvas.
;AgentVector:An aggregating component that manages its members as agents moving over a cartesian or hexagonal plane.
;aggregator:Also aggregating container and aggregating component. Refers to CellMatrices, AgentVectors, SimWorlds, NodeNetworks and NetWorlds. Aggregators hold multiple instances of their elements and create a virtual topology within which the elements operate. Members of aggregating containers must be Capsules.
;atomic component:Components such as Stocks, Terms, Flows, Commands, Codechips, etc., that do not have sub-components. They can only be members of Capsules.

==C==

;Capsule:Prototype for a simulation unit. Capsules contain interacting base and aggregating components, and chips, and may contain inputs and outputs.
;Capsule Interface:Also referred to as Interface. The set of DataInput and DataOutput components in a Capsule. They corrspond to pins in the enclosing Container.
:capsule set:The window of the Application Interface where the capsules of a model are listed.
;capture:A button that converts the visual representation of a NumerusMB model into a script.
;CellMatrix:An aggregating component that creates a two-dimensional cartesian or hexagonal topology with its members.
;cellular automaton:A type of spatially explicit model where space is represented as a two-dimensional finite grid and each cell has a discrete state.
;Chip:A Container component which contains a single Capsule for membership in a parent Capsule.
;Clock:A special object for maintaining model time and providing strobe signals to the components.
;Clocked Chip:A Chip with which a new Clock has been associated. Each strobe on the Chip produces a complete run of the enclosed Capsule instance based on the parameters of the associated Clock.
;Codechip:A programmable component with user-specified inputs and outputs.
;Command:A NumerusMB component containing executable code that changes the state of the program.
;component equation:Also called component expression. One or more lines of code included as a component property that defines the value of that component.
;console:The window of the Application Interface where you can enter commands one at a time.
;Container:Chip or aggregator component. A Container holds one or more Capsule instances (or submodels). The latter are called elements or members of the Container
;converter plug-in:A plug-in used to compute values used in updating the current state.
;Coords:Refers to a JavaScript object that contains fields row and col, representing matrix row and column values.

==D==

;delta value:The amount of time between state updates; also called dt.
;deterministic model:A model where the outcome is fully predictable from the initial state (i.e., no random effects).
;display plug-in:A plug-in used only for visualization.
;dynamic systems model:A model of a system that changes over time.

==E==

;Euler Method:A method of numeric integration that estimates P(t) as P(t-t) + P(t-t)t, where t is the change in time. Pronounced "Oiler method".

==F==

;field:A property-name/property-value pair in a JavaScript object. Also refers to a stateful variable in a CodeChip.

==G==

;global segment:Section of the Programming Window containing global definitions.

==I==

;identifier:A text string (beginning with a letter) used as a property or local variable.
;integration method:Procedure used to iterate from ''t'' to ''t + dt'' when considering continuous functions.
;Interface:See [[#C|Capsule Interface.]]
;iteration:Step from time ''t'' to ''t + dt'' in the simulation.

==L==

;local variable:An identifier used as a variable within a specific Capsule instance.
;local variable segment:Section of the Programming Window containing local variables.

==M==

;member:Constituent of a Container.
;method:An object field that contains a function.
;method segment:Section of the Programming Window containing local methods.
;Model Canvas:The window of the Application Interface where the model is graphically designed and built from components.
;model time:Local simulation time in units determined by the model.
;Monte-Carlo:A model involving an element of chance (i.e., randomness).

==N==

;NetViewer:A plugin used to visualize the nodes in a network; either a NodeNetwork or NetWorld.
;NetWorld:An aggregating component that contains an AgentVector and NodeNetwork. The NodeNetwork determines the network topology where the agents exist.
;NodeNetwork:An aggregating component that creates a network (i.e. mathematical graph) topology in which its members are nodes.
;NumerusScript:A scripting language that was created specifically for designing and running models. NumerusScript is an extension of JavaScript.

==P==

;parent:Another name for the host of an aggregator.
;plug-in:A user-defined extension to NumerusMB that adds a new component type.
;post-processing (post-process):Actions required during the post-update phase.
;post-update:Actions taken after the current state is changed during an iteration.
;pre-update:Actions taken before the current state is changed during an iteration.
;primop:Short for primitive operator; a built-in JavaScript or NumerusScript function.
;Programming Window:The section of the NumerusMB interface in which the user may add code.
;project:All of the capsules, functions, clock settings, etc. associated with a model. When you open NumerusMB, you are working on a project.
;property:An identifier whose value is fixed throughout the simulation.
;property segment:Section of the Programming Window containing local properties.

==R==

;RunData:A special NumerusScript object that contains all of the output from a Stock during a complete run. Used to accumulate statistics.
;Runge-Kutta 2 Method:A method of numeric integration that employs a correction to each Euler method estimate.
;Runge-Kutta 4 Method:A method of numeric integration, where each approximation is weighted average of four estimates.

==S==

;schema or scenario:NumerusScript object used for defining a component. Acts like a class declaration for NumerusScript objects.
;self:state object binding referencing the component object.
;Self:Pointer to the state object of a simulator.
;simulation:A sequence of state transitions from a start time to an end time using a fixed time increment dt.
;simulator:Capsules, CellMatrices, AgentVectors SimWorlds, NodeNetworks and NetWorlds, all of which have constitutent members.
;SimWorld:An aggregating component containing a CellMatrix and AgentVector, in which the CellMatrix serves as the cartesian or hexagonal space in which the AgentVector's agents exist.
;start time:Point in model time when the simulation starts (usually 0).
;State Object:A special object referenced from Self in a simulator. For Capsules, it contains the current value for each member; for aggregating components it provides methods for obtaining the state object of members.

==W==

;wrap:The practice of treating coordinates outside the dimension of a cartesian space as continuing from the opposite boundary. Topologically, the resulting space becomes a torus.
