SUMMARY
A "stencil" in finite difference methods refers to the computational molecule used to calculate the next point in a numerical solution. Specifically, for the Euler method applied to ordinary differential equations (ODEs), the stencil is defined as u_{n+1}=u_{n}+hf(x_{n},u_{n}). In the context of partial differential equations (PDEs), stencils become more complex, involving multiple points and relationships. Understanding stencils is crucial for implementing finite difference methods effectively.
