Partial Differential Equation Terms

Topic
Overview  »

The Wolfram Language has powerful functionality for solving a wide variety of partial differential equations both symbolically and numerically. The symbolic capabilities of the Wolfram Language make it possible to efficiently set up PDE equations expressed as PDE terms that can be used by themselves or used as building blocks for assembling larger PDE components.

For specific physics fields, relevant PDE terms have been packaged as components and augmented with boundary condition functions typically encountered in the field.
