- EISPACK
- A collection of Fortran subroutines that compute the eigenvalues and eigenvectors of nine classes of matrices: complex general, complex Hermitian, real general, real symmetric, real symmetric banded, real symmetric tridiagonal, special real tridiagonal, generalized real, and generalized real symmetric matices. In addition, two routines are included that use singular value decomposition to solve certain least-squares problems.

- Laso
- Fortran IV subroutines for computing a few eigenvalues of a large (sparse) symmetric matrix.
- 3665
- SLEIGN2
- Code to compute eigenvalues and eigenfunctions of regular and singular self-adjoint Sturm-Liouville problems.
- 3667
- Blended Implicit Methods (BiM)
- Fortran 77 code implementing a variable order-variable stepsize method for (stiff) initial value problems for ODEs. The order of the method varies from 4 to 14, according to a suitable order variation strategy.

- DVERK
- Fortran 77 subroutine written by Hull, Enright and Jackson for the numerical solution of systems of initial value problems for ordinary differential equations.
- 3670
- Initial Value Problems
- The code GAM numerically solves solves first order ordinary differential equations, either stiff or nonstiff in the form y'=f(x,y), with a given initial condition. The code GAMD is a generalization of GAM for the solution of Differential Algebraic Equations of index less than or equal to 3 in the form M y' = f(x,y), with a given initial condition. By Francesca Mazzia.

- FUN2D/3D
- Describes a Fortran 95 code for solving the Navier-Stokes equation on a fully unstructured grid.

- Multiresolution schemes
- Program by Sorin Mitran to solve the 1D Euler equations using Harten's multiresolution algorithm.

- Parallel Hierarchical Adaptive MultiLevel Project (PHAML)
- Fortran 90 code using adaptive refinement, multigrid and parallel computing to solve 2-D linear elliptic PDEs. Successor to MGGHAT.
- 3678
- MultiGrid Galerkin Hierarchical Adaptive Triangles (MGGHAT)
- Solve second order two dimensional elliptic partial differential equations, using adaptive refinement of second, third, or fourth order elements, and multigrid solution techniques.
