a stated restriction, usually in the form of an equation, that limits the possible solutions to a differential equation.
Examples from the web for boundary condition
To provide the initial and lateral boundary condition files by interpolating larger scale model data to the domain.
The implementation of this boundary condition is primarily aimed at simulating infiltration on land surface with possible ponding.
Of particular interest in applications is the free surface boundary condition, where the normal stress is set to zero.
The internal boundary condition includes only two flow-path end nodes in this case.
Choosing a constant or flux boundary for the inflow boundary condition will make a difference.
Any one-node control structure can serve as an external boundary condition.

boundary condition
(boun'də-rē) Mathematics The set of conditions specified for the behavior of the solution to a set of differential equations at the boundary of its domain. Boundary conditions are important in determining the mathematical solutions to many physical problems.
