Partial Differential Equations |

The "FInite DIfference SOLver/Cartesian Arbitrary Domain SOLver" is a program package for the solution of partial differential equations. 2- and 3-dimensional systems of elliptic (stationary) and parabolic (time-dependent) equations can be solved. The boundary conditions may be arbitrary. The solution method is the finite difference method. For the FIDISOL part the solution domain is restricted to be rectangular. For the CADSOL part the domain is body-oriented, i. e. logically rectangular. There are versions with an adaptive grid generation. For CADSOL dividing lines can be prescribed allowing the solution of different partial differential equations in different subdomains or allowing noncontinuous conditions inside the domain.
Compatible with Lahey ELF90 (Fortran 90 subset) compiler.
Solution of PDEs using pseudospectral (collocation) methods.
Parallel Fortran 90 module to solve positive-definite elliptic linear second-order operator systems.
Modular general-purpose package written in Fortran 77 for the numerical solution of systems of differential-algebraic equations and 1D partial differential equations. It is used at Shell Research Laboratories and at several UK, Europe and North American Universities, and it forms the basis of the underlying solver in the SPRINT2D and SPRINT3D software.
Collection of vectorized, portable Fortran 77/90 subprograms which efficiently solve linear elliptic PDEs using multigrid iteration. OpenMP directives are used in the latest version to enable shared memory parallelism.
Collection of Fortran subprograms which utilize cyclic reduction to directly solve second- and fourth-order finite difference approximations to separable elliptic PDEs in a variety of forms.
Fortran 90 code using adaptive refinement, multigrid and parallel computing to solve 2-D linear elliptic PDEs. Successor to MGGHAT.
Codes from books of W. E. Schiesser. Some are online, others are available upon request.
Fortran 77 package by Jiri Zahradnik for 2-D P-SV elastic second-order finite differences.
