In this case a reservoir flow can be analytically modeled with infinite boundary reservoir:
| Linear Flow | Radial Flow | ||||||||
|---|---|---|---|---|---|---|---|---|---|

Numerical model always performs calculations with finite boundary.
There are hybrid models which perform numerical calculations in finite volume composite and infinite boundary analytical model outside the composite.
A typical example is 3D flow simulations with infinite aquifer.
