Trilinos Home Page

Welcome to the Trilinos Project Home Page

The Trilinos Project is an effort to develop algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems. A unique design feature of Trilinos is its focus on packages.

What Trilinos Can Do: Trilinos Capability Areas

The Trilinos Capability Area homepage organizes Trilinos capabilities into nine collections of functionality and describes which packages are relevant to each area. This discussion is especially useful for new Trilinos users.

Trilinos is on GitHub

The primary Trilinos repository is now hosted on GitHub. This allows users and potential developers greater access to Trilinos source code.

TUG 2019

The 2019 Trilinos User Group Meeting (TUG) is held in October in Albuquerque.

Trilinos v12 Code Deprecation

Trilinos announces 37 code deprecations in 16 packages. Code removal from the Trilinos develop branch will begin November 15, 2019. See the Trilinos v12 Deprecation Document for details.

Trilinos 12.12 Release

Trilinos 12.12 is now available for download. The 12.12 release uses a CMake build system, which requires CMake version 2.8.11 or greater. Instructions for building Trilinos 10.0 and later are available here.

Trilinos Packages

Each Trilinos package is a self-contained, independent piece of software with its own set of requirements, its own development team and group of users. Because of this, Trilinos itself is designed to respect the autonomy of packages. Trilinos offers a variety of ways for a particular package to interact with other Trilinos packages. It also offers a set of tools that can assist package developers with builds across multiple platforms, generating documentation and regression testing across a set of target platforms. At the same time, what a package must do to be called a Trilinos package is minimal, and varies with each package.
